I assume you mean x squared in the first equation
Because both are equal to y, they are equal to each other so x + 5 = x^2 +3
If we then move everything over to one side, we get x^2 - x - 2 = 0
Then factorise it to (x-2)(x+1) = 0
And solve both parts separately
x + 1 = 0
x = -1
x-2 = 0
x = 2
Sub both values into the simplest equation in this case y=x+5
to get y = 4 and y = 7
Answer:
(11 ft)³
Step-by-step explanation:
Given the shape is a cube, all of its sides are the same.
The formula for the volume of a cube is V = s³ where "s" represents the edge length.
Substitute "s" for 11 ft.
V = s³
V = (11 ft)³
In exponential form, do not solve for the volume. Leave the expression as
(11 ft)³
Without the units, the answer is 11³
