Answer:
(x + 3b)(3 + 5a)
Step-by-step explanation:
Assuming you require the expression factorised.
Given
3x + 9b + 5ax + 15ab ( factor the first/second and third/fourth terms )
= 3(x + 3b) + 5a(x + 3b) ← factor out (x + 3b) from each term
= (x + 3b)(3 + 5a) ← in factored form
Answer: 40 mi/h
Step-by-step explanation:
it goes up 80 and over 2, so the rate of change is 80/2 = 40 mi/h
52m^2= 2[(x-5)+(x)]. 52m^2= 2(2x-5). 52m^2=4x-10
Answer:
a = 16 and b = 2
Step-by-step explanation:
The area is (27 x 3) + (15 x 7) = 186
