The formula for the volume of a square pyramid is
v = (b2h) - 3, where b is the length of one side of the
square base and h is the height of the pyramid. find the
length of a side of the base of a square pyramid that has
a height of 3 inches and a volume of 25 cubic inches.

5 inches

Step-by-step explanation:

The volume of the square pyramid is given by:

where b is the length of one side of the

square base and h is the height of the pyramid.

The height is given as h=3 inches and volume, V=25 cubic inches.

We substitute and solve for b

Take principal square root to get:

inches.

Hence the length of a side is 5 inches.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
