Answer: True
=================================================
x^2 = x*x
5x = 5*x
Both x^2 and 5x have a factor of x in common
x^2 + 5x = x*x + 5*x
x^2 + 5x = x*x + x*5
x^2 + 5x = x*(x+5) .... use the distributive property in reverse
x^2 + 5x factors to x*(x+5)
As a way to check, you can distribute the x back in
x*(x+5) = x*x + x*5
x*(x+5) = x^2 + 5x
and we get the original expression again
Answer:
a = 15
Step-by-step explanation:
Plug in b = 3 into 5a-10b=45
5a-10(3) =45
5a - 30 = 45
5a = 75
a = 15
