It's very simple: It's the surface of a base times the height

Answer:
Step-by-step explanation:
y=kx
4=k(-2)
k=-2
y=-2x
when x=30
y=-2*30=-60
Tan(35)=x/12
.7=x/12
12*.7=x
x=8.4
A 3 1/3
Subtract
8x-2-5x=8
-5x
3x-2=8
+2 +2
3x=8
X=10/3
Answer:

Step-by-step explanation:
Given
(5x - 3y)² = 0, then
5x - 3y = 0 ( add 3y to both sides )
5x = 3y (divide both sides by 5 )
x =
y ( divide both sides by y )
=
