Draw a rectangle with each side saying 5cm
To solve for n:
n/3+5=7
Subtract 5 from both sides.
n/3=2
Multiply both sides by 3.
n=6
Hope this helps! :)
Answer: posted this question to help y’all Because I couldn’t find the answer myself. you can see it was correct at the bottom :)
Step-by-step explanation:
good luck!
Factor the following:
5 x^2 + 20 x + 15
Factor 5 out of 5 x^2 + 20 x + 15:
5 (x^2 + 4 x + 3)
The factors of 3 that sum to 4 are 3 and 1. So, x^2 + 4 x + 3 = (x + 3) (x + 1):
Answer: 5 (x + 3) (x + 1)
