The sum of 2 numbers is equal to 63 and their difference is equal to 12. Find the numbers

Answers

Answer 1

Answer:

X=37.5

Y=25.5

Step-by-step explanation:

Assume first number is x and second is y, according to the question:

x+y=63

x-y=12

Adding two equation together:

2x=75

x=37.5

37.5-y=12

y=25.5

Answers

C. X > -1

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2x + 5 < 7

Step 2: Subtract 5 from both sides.

−2x + 5 − 5 < 7 − 5

−2x<2

Step 3: Divide both sides by -2.

−2x/−2 < 2/−2

x > −1

It would be C X > -1

Answers

You can write such a cubic polynomial in terms of its roots using the factor theorem:

(x - (-1)) (x - 3) (x - (-5)) = (x + 1) (x - 3) (x + 5)

Now just expand this:

(x + 1) (x - 3) (x + 5) = x ³ + (1 - 3 + 5) x ² + (-3 + 5 - 15) x - 15

… = x ³ + 3x ² - 13x - 15

Answer:

  37°

Step-by-step explanation:

The diagonals of a rhombus are angle bisectors. Angle 1 matches the other half of angle L.

  ∠1 = 37°

__

Angle 2 is the complement, 53°, and angle 3 is the same as angle 2, 53°.

The diagonals of a rhombus are perpendicular bisectors of each other, so angle 4 is 90°.

2. This is Josh’s solution for the equation :

Is Josh’s solution correct? Explain.

Answers

Answer:

x = 7

Step-by-step explanation:

in Josh solution, the steps are correct till

(x-3)² = 16. After this

√(x-3)² = √16

x-3 = 4

x = 4+3 = 7

No, Josh is incorrect the roots of the quadratic equation are 19 & -13.

What is a quadratic equation ?

An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.

Given that,

The quadratic equation,

x²  - 6x - 7  = 0

we can calculate the roots of the equation by using the formula:

x   = -b + √(b² - 4ac) / 2a

In the given equation,

a = 1

b = -6

c = -7

x  = -(-6)  + √((-6)² - 4x1x(-7)) / 2

  =    (6 + 8)/ 2

x =   7,  -1

Hence, Josh's solution is not correct.

Answer:

130.5ft²

Step-by-step explanation:

Hello There!

The figure shown is a composite figure ( so we can't find the area of it using one formula )

That being said we want to break the irregular figure into regular figures in which the area can simply be found using a formula

The figure would be broken in to the following shapes

A rectangle with a width of 4 ft and a length of 9 ft

A rectangle with a width of 8 ft and a length of 9 ft

A triangle with a height of 5 ft and a base of 9 ft

Now that we have broken the irregular figure into regular shapes we want to find the area of each individual shape

For the smaller rectangle:

The area of a rectangle can simply be calculated by multiplying the width and length

So A = 9 * 4

9 * 4 = 36

so the area of the smaller rectangle is 36ft²

For the larger rectangle

Once again the area can simply be found by multiplying the width and length

A = 8 * 9

8 * 9 = 72

so the area of the larger rectangle is 72ft²

For the triangle

To find the area of a triangle we want to use this formula

[tex]A = \frac{bh}{2}[/tex]

where b = base and h = height

We have already identified the base and height so all we have to do is plug in the values into the formula

[tex]A=\frac{5*9}{2} \\5*9=45\\\frac{45}{2} =22.5[/tex]

so the area of the triangle is 22.5ft²

Finally we add the areas of each regular figure

22.5 + 72 + 36 = 130.5

so we can conclude that the area of the composite figure is 130.5ft²
