3. Then:
Answer:
4/31
Step-by-step explanation:
Im.not too sure about the answer but i think its that
For the first one, x=-1, y=-8
A = 1/3 * s^2 * h where s is a side of the base and h is the height.
C.
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 77, -77
