Your answer would be B. 247 ft².
This is because if you draw the prism out, you can use the dimensions to find the individual surface areas, and then add them together.

So you would do 10 × 6 = 60, and then multiply it by 2 as there are two of each side to get 120 ft².
6 × 4 = 24, and then multiplied by 2 = 48 ft².
10 × 4 = 40, multiplied by 2 = 80 ft².

Then when you add together 120, 80, and 48, you get 248 ft².
I hope this helps!

A = 2( wh + lw+ lh)

= 2( 6 *10 + 4*6 + 4*10)

= 2* 124

= 248

The answer therefore is B, 248 ft^2

Given f(x) = 10 -2xfind f(7). –4 3 7 56
strojnjashka [21]

Answer: f(7)=-4

Step-by-step explanation:

1. You have the following function given in  the problem:

f(x)=10-2x

2. Then, to find f(7) asked in the exercise, you only need to substitute x=7 (which is the input value) into the given function.

3. Therefore, keeping the above on mind, you obtain that f(7) is:

x=7

f(7)=10-2(7)

f(7)=10-14

f(7)=-4

I need help with this question ASAP!!!!!!!!!!!!!

The height of the flag pole is 51 ft.

Solution:

Paul creates the smaller triangle and flag pole creates the larger triangle.

Base of smaller triangle = 10 ft

Height of smaller triangle = 6 ft

Base of the larger triangle = 85 ft

Let the height of the flagpole be h.

$\Rightarrow \frac{6}{10} =\frac{h}{85}

Multiply by 85 on both sides.

$\Rightarrow 85 \times \frac{6}{10} =\frac{h}{85}  \times85

$\Rightarrow \frac{510}{10} =h

⇒ 51 = h

The height of the flag pole is 51 ft.
