Answer:

Step-by-step explanation:

15x² = 3⋅5x²

9xy = 3²xy

15x² + 9xy + 3x = 3x(5x + 3y + 1)

The factored form of the expression 15x² + 9xy + 3x is 3x(5x + 3y + 1).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To factorize 15x² + 9xy + 3x, we can factor out the greatest common factor of the three terms, which is 3x:

15x² + 9xy + 3x = 3x(5x + 3y + 1)

Therefore,

The factored form of 15x² + 9xy + 3x is 3x(5x + 3y + 1).

Exact: [tex] 11 \pi~in.^2 [/tex]

Approximate: [tex] 34.6~in.^2 [/tex]

Step-by-step explanation:

The spaces the clocks occupy on the wall are the areas of the clocks.

The clocks are shaped like circles, so use the formula for the area of a circle to find the two areas. Then subtract the smaller area from the larger area.

[tex] A_{circle} = \pi r^2 [/tex]

Larger clock, r = 6 in.

[tex]A_{large~clock} = \pi \times (6~in.)^2 = 36 \pi ~in.^2 = 113.1~in.^2[/tex]

Smaller clock, r = 5 in.

[tex]A_{small~clock} = \pi \times (5~in.)^2 = 25 \pi ~in.^2 = 78.5~in.^2[/tex]

Difference in areas:

Exact: [tex] 36 \pi~in.^2 - 25 \pi~in.^2 = 11 \pi~in.^2 [/tex]

Answer:

Opposite faces are parallel

There are 6 faces

All faces meet at 90 degrees.

Step-by-step explanation:

I think

The angles x°, 2x°, and (x + 10)° are complementary angles. Then the value of the variable x will be 20°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

The angles x°, 2x°, and (x + 10)° are complementary angles.

Then the sum of the angles x°, 2x°, and (x + 10)° will be 90°.

Then the equation will be

x° + 2x° + (x + 10)° = 90°

Simplify the equation, then the value of x will be

4x + 10 = 90

      4x = 80

        x = 20°

Thus, the value of the variable x will be 20°.

Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x

Step-by-step explanation:

So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4  $11.38 reflectors are purchased as well as gloves for 31.41.  Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.

We are required to write an inequality for the problem and also solve it

The number of biking outfit Ethan can purchase is 2

Given:

Total amount Ethan has = $620

Amount of bicycle = $427.57

Bicycle reflector = $11.38

Cost of 4 Bicycle reflector = $11.38 × 4

= $45.52

Cost of bike glove = $31.41

Cost of biking outfit = $57.75

Write an inequality to solve for the number of biking outfit Ethan can purchase

let

x = number of biking outfit Ethan can purchase

620 ≥ 427.57 + 45.52 + 31.41 + 57.75x

620 ≥ 504.5 + 57.75x

620 - 504.5 ≥ 57.75x

115.5 ≥ 57.75x

x ≥ 115.5 / 57.75

x ≥ 2

https://brainly.com/question/21866486

Answer:

One angle is 26 degrees and the other is 64 degrees.

Step-by-step explanation:

Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:

90 = (x-38) + (x)

52 = 2x

26 = x

This means that one of the angles is 26 degrees, and the other is 64 degrees.

Step-by-step explanation:

Explanation: y=3x+2 is not a function. Rather, it is just a regular linear equation.

It's not.

Explanation:

y=3x+2

is not a function. Rather, it is just a regular linear equation. However,

f(x)=3x+2

is a function, because it contains "

f(x)."

So, in general, if it contains " y ," then you are safe in assuming that it is an equation. If it contains "

f(x) ," then you are safe in assuming that it is a function.

I hope that helps!

The function y = 3x - 2 is a linear function.

Given data:

The function is represented as y = f ( x )

The value of y = 3x - 2

The equation y = 3x - 2 represents a linear function.

The function has a constant rate of change, which is 3, as the coefficient of x. The function forms a straight line when graphed on a Cartesian coordinate plane.

The term "linear" indicates that the relationship between x and y is of the first degree, meaning there are no exponents or other nonlinear components involved.

The number of medium bags will be 410 / 3.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that Jill puts 440 sweets into small bags, medium bags and large bags. She uses 30 small bags

The equation can be written as,

L + M + S = 440

L = 2M

2M + M + 30 = 440

3M = 410

M = 410 / 3

Therefore, the number of medium bags will be 410 / 3.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    1/3+a-(5/4*a)=0

                 5

Simplify   —

                 4

    1                 5

 ( — +  a ) -  ( — • a )  = 0

   3                 4

                 1

Simplify   —

                 3

Solve  :    -3a+4 = 0

Subtract  4  from both sides of the equation :

                     -3a = -4

Multiply both sides of the equation by (-1) :  3a = 4

Divide both sides of the equation by 3:

                    a = 4/3 = 1.333

Step-by-step explanation:

- In a right triangle, if ∠B is 45°, then ∠C is too.

-- Since ∠B  and  ∠C  are equal, the sides opposite them

are equal too.  This is an isosceles right triangle.  Its legs

are equal.

-- (The hypotenuse)²  =  (one leg)²  +  (the other leg)²

                                  =       (12-ft)²  +  (12-ft)²

                                  =              (144 x 2)

     The hypotenuse  =  √(144 x 2)  =  12√2 .
