area of square = 9 x 9 = 81 square feet
area of 1 corner = 1/2 * 3 * 3 = 4.5 square feet
4.5 * 4 = 18 square feet total of all 4 corners
81 - 18 = 63 square feet total not covered by benches.

Hi there!
The correct answer to this question is: The <u>surface area</u> of the prism is 456 cm^2. The <u>volume</u> of the prism is 408 cm^2
Try to use the total which is 650 - 247
by that will give you the answer
Answer:
2x + 10
Step-by-step explanation:
To expand (using the distributive property) <u>multiply</u> the number outside the bracket i.e. in this case '2', with the <u>values inside the brackets</u>.
So multiply '2' and 'x' and '2' and 5' and add or subtract on basis of whether the second value is positive or negative.
So
2(x + 5)
= (2*x)+(2*5)
=2x+10
<em>extention note:</em> <u>be careful</u> when the symbol within the equation within the brackets is a subtraction because it implies that the second value would instead be a negative number and should be treated as such.
an example
2(x-5)
= (2*x)+(2*-5)
=2x -10
Anyhow, I hope this helped!
Answer:
<h2>90</h2><h2 />
Step-by-step explanation:
see attached image.
internal angle must be equal to 180
- ∠2 + 33 + 57 = 180
- ∠2 = 180 - 57 - 33
- ∠2 = 90
