8 0

Answer:

Step-by-step explanation:

4

If you put 4 with another 4 the total is 8. The two lines must be greater than the third. Equal is not good enough.

The other lengths will produce triangles with 4 and 8. Any 2 will be greater than the third.

A swimming pool is a rectangular prism. The pool is 36 feet long and 20 feet wide. What is the total amount of water, in cubic f
Sliva [168]

Answer:

2880\ ft^{3}

Step-by-step explanation:

The computation of the total amount of water needed could be determined by using the volume formula which is shown below:

Volume = L \times W \times D

where

L = length,

W = width,

and D = depth.

Now putting the values to the above formula

Volume = (36\ ft) \times (20\ ft) \times (4\ ft) \\\\= 2880\ ft^{3}                            

Therefore, the  total amount of water needed is 2880\ ft^{3}

We simply applied the above formula

Eva8 [605]

Given:

The given expression is:

(-4x+9)^2

According to Kylie,

(-4x+9)^2=(-4x)^2+(9)^2

(-4x+9)^2=16x^2+81

To find:

The correct statement for Kylie's explanation.

Solution:

We have,

(-4x+9)^2

According to the perfect square trinomial (a+b)^2=a^2+2ab+b^2.

(-4x+9)^2=(-4x)^2+2(-4x)(9)+(9)^2

(-4x+9)^2=16x^2-72x+81

Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.

Therefore, the correct option is C.
