Answer:
60
Step-by-step explanation:
We can use the pythagorean theorem to find the leg.
10^2+x=13^2
x=12
We now find the area given the height of the triangle.
10 X 12=120
120/2=60
Answer:
10x^2 -4x +6
Step-by-step explanation:
The area of the blue square is
2* 5x^2 = 10x^2
The area of the pink square is
2 * -2x = -4x
The area of the green square is
2 *3 = 6
Add it all together
10x^2 -4x +6
You add 70 + 50 then you multiply it by 7.5 and you get, 900 gallons.
