Answer:
x(12x^2+18x)
Step-by-step explanation:
x(12x^2+18x)=12x^(3)+18x^2
Answer:
w=30 l=125
Step-by-step explanation:
Perimeter =2l+2w
p=310
w =width
4w+5 = length(4 times plus 5 the width)
2(4w+5) + 2w = 310
8w+10 = 2w =310
10w=300
w=30
30*4=120 120+5=125 l=125
2(125)+ 2(30)= 250+60 =310
X² - x - 20
x² -5x+4x - 20
x(x-5) +4(x-5)
(x+4) (x-5)
