If x = 2 and y=5, what is the value of the expression below?
7x + y2
a. 24
b. 39
c. 82
d. 97

Answer:

They will mirror each other, but only if they have the same y value. Otherwise they will simply be on opposite sides of the Y line.

Hope this helps :)

Answer:

[tex]Area = 4h^2-56h +144[/tex]

Step-by-step explanation:

Given

See attachment for complete question

Required: The base area.

From the question, we have the initial dimensions to be:

[tex]Length = 12[/tex]

[tex]Width = 12[/tex]

h inch were removed from each corner to form the new base. So, the dimension of the new base is:

[tex]Base\ Length = Length - h - h[/tex]

[tex]Base\ Length = Length - 2h[/tex]

[tex]Base\ Width = Width - h-h[/tex]

[tex]Base\ Width = Width - 2h[/tex]

The area of the base is calculated by multiplying the base dimensions

[tex]Area = Base\ Length * Base\ Width[/tex]

[tex]Area = [Length - 2h] * [Width - 2h][/tex]

[tex]Area = [12 - 2h] * [12 - 2h][/tex]

Expand

[tex]Area = 12[12 - 2h] -2h [12 - 2h][/tex]

[tex]Area = 144 - 28h -28h + 4h^2[/tex]

[tex]Area = 144 -56h + 4h^2[/tex]

Rewrite as:

[tex]Area = 4h^2-56h +144[/tex]

Answer:

1. 3

2. depends on the lenght of each cube i dont know so just multiply it with 3

3. same here or by 2 i dont know which side to get the width of sorry

Answer:

The answer is D

Step-by-step explanation:

Answer:

D) Quadrant IV (quadrant 4)

Step-by-step explanation:

Point C is in quadrant IV because its point is (4,-4)

For points that have a positive x-coordinate and a negative y-coordinate, that means they are in quadrant IV.

Another way to figure this out is by looking at this graphically:

                                    y

                                    |

         Quadrant           |          Quadrant

                II                  |                 I

                                    |

 ------------------------------|----------------------------- x

                                    |

          Quadrant          |           Quadrant

                III                 |                 IV

                                    |

Answer:

42 (d)

Step-by-step explanation:

the longest side of the smaller one is 6, each side of the larger one is just 3x the length of the smaller side. I hope that makes sense, it's just a ratio. Hope this helped! Good luck!

Answer:

The perimeter of the larger triangle is 42 inches.

Step-by-step explanation:

Since the question mentions that the two triangles are similar, we must establish proportions using what we already know.

Smaller triangle: 3 + 5 + 6 = 14

Larger triangle: x + y + 18 = perimeter

Determine the GCF (greatest common factor):

The GCF is 3.

Now, subsitute the values for x and y by solving via the GCF.

Larger triange:  9 + 15 + 18 = perimeter

9 + 15 + 18 = 42

Hope this helps; have a wonderful day!

Answer:

d = 225 m

Step-by-step explanation:

Initial speed, u = 5 m/s

Final speed, v = 40 m/s

Time, t = 10 s

Acceleration,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{40-5}{10}\\\\a=3.5\ m/s^2[/tex]

Let d is the distance covered. Using second equation of motion to find it i.e.

[tex]d=ut+\dfrac{1}{2}at^2\\\\d=5\times 10+\dfrac{1}{2}\times 3.5\times 10^2\\\\d=225\ m[/tex]

So, it will cover 225 m.

Answer:

There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.

As we have to find 5 rational numbers between 1 & 2

Take 5 and add 1 to it i.e. 5+1= 6

Now take the first number and multiply and divide it by 6 i.e.

1x6/6 = 6/6

Also take the second number and multiply and divide it by 6 i.e.

2x6/6= 12/6

This is done to convert 1 & 2 into rational number i.e. in form of p/q

Now we have two numbers 6/6 and 12/6 so five rational numbers between them are

7/6, 8/6, 9/6, 10/6, 11/6

The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.

Answer:

m<D = 52°

Step-by-step explanation:

x + 20 + 3x + 32 = 180

4x + 52 = 180

4x = 128

x = 32

m<D = x + 20 = 32 + 20 = 52°

Answer:

5.4 units

Step-by-step explanation:

The diagonal AC has length

|AC|  =  √(2² + 5²) = √29 ≈ 5.4 units.

The horizontal distance from A to C is 2 units; the vertical distance is 5 units.  That's where the 2² and 5² come from.  

Answer:

[tex]f(4x)=-8x+5[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=-2x+5[/tex]

And we want to find:

[tex]f(4x)[/tex]

So, by substitution, we acquire:

[tex]f(4x)=-2(4x)+5[/tex]

Multiply. So, our answer is:

[tex]f(4x)=-8x+5[/tex]
