Answer:
Whatever you do to one side you must do it to the other side of the equation.
Step-by-step explanation:
Answer is B.
hope it helps
Area = 1/2 b * h
h = b - 9
b = b
Area = 56cm^2
Area = 1/2 (b - 9) * b
56 = 1/2 (b^2 -9b)
112 = b^2 - 9b
b^2 - 9b - 112 = 0
b = 16 and therefore the height is
h = 26 - 9 = 7
Check
Area = 1/2 * 16 * 7
Area = 8 *7
Area = 56 which checks.
Answer:
(x + c) (x - c)
Step-by-step explanation:
For any number the polynomial 
can be factored as (x + c) (x - c)
Answer:
64
Step-by-step explanation:
The volume of rectangular prisms is measured by l*w*h
And by counting the units of the length, width, and height are all 4 units long.
So take the numbers and plot them into the formula
4*4*4 = V
16 * 4 = V
64 = V
The prism is 64 cubic units.
