Answer: 34.93 units
Step-by-step explanation:
The volume of a rectangular prism can be calculated with this formula:
Where "V" is the volume, "B" is the base area and "h" is the height.
Since we need to find the height, we must solve for "h":
We know that the volume of that wooden chest (which is in the shape of a rectangular prism) is 524 cubic units and the base area is 15 square units. Then:
Subsitituting these values into , we get that the height of the chest is:
Answer:
A
Step-by-step explanation:
Given
x² - x = 30
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- )x +
= 30 +
(x - )² =
Take the square root of both sides
x - = ±
= ±
Add to both sides
x = ±
, thus
x = -
= - 5
x = +
= 6
