Use the formula for the volume of a triangular pyramid: V=13Ah , where A = area of the triangular base, and H = height of the pyramid.
Answer:
The required option are
Length = 4 and width = x+5
Length = 2 and width = 2x+10
Step-by-step explanation:
Area of the rectangle = Length × width
Given
Area = 4x+20
Factoring out the common terms
Area = 4x + 4(5)
Area = 4(x+5)
Length = 4 and width = x+5
This can also be written as
Area = 2(2x+10)
Length = 2 and width =2x+10
Answer:
7/2 and 3
Step-by-step explanation:
using quadratic formula
{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)
-(-13)+1 / 4 = 7/2
-(-13)-1 / 4 = 3
