Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
Answer:
4%
Step-by-step explanation:
(|600-625|)/625 x 100
=4%
Answer:
20
Step-by-step explanation:
3x + x + 100 = 180 (sum of angles on a straight line)
4x = 180-100
4x=80
divide both sides by 4
x=20
Answer:
x + 600 ≥ 2400
Step-by-step explanation:
Given:
Amount needed = $2,400
Amount they had = $600
Find:
Amount they need
Computation:
Assume;
Amount they need = x
x + 600 ≥ 2400
