The area of a parallelogram is given by the formula A = bh where is the base and h is the height. A parallelogram has an area of 312 square centimeters and a base of 26 centimeters. Find the height of the parallelogram in centimeters.

12

Step-by-step explanation:

to find area, you do bxh(aka base x height)

since it didn't give you the height but the length and area,you have to divide.

312 ÷ 26=12

Hoped this helps!!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
