If you want to find the surface area of something and it doesn't have a formula, just look at the area of each side individually and add them up!
The area of a triangle is equal to bh/2 = 16*6/2 = 48 in²
The area of the other triangle would be the same = 48 in²
The lateral side that's 10 by 9 inches = 10 * 9 = 90 in²
The other lateral side that's 10 by 9 is also = 90 in²
The lateral side that's 16 by 9 inches = 16 * 9 = 144 in²
144 + 90 + 90 + 48 + 48 = 420 in²
Answer:
x^3 + 4x^2 - 7x - 10
Step-by-step explanation:
To solve this we're going to use Polynomial multiplication, starting by multiplying (x-2)(x+1) = x^2 - 2x + x - 2 = x^2 - x - 2. Next, we will multiply (x^2 - x - 2)(x+ 5) = x^3 + 5x^2 -x^2 - 5x -2x -10 = x^3 + 4x^2 - 7x - 10.
Answer:
8
Step-by-step explanation:
Multiply 11 by 2 to get to 22; do the same to 4
1,4
it’s y1-y2
———-
x1-x2
I think the answer would be 17 pies
