7.2
8.6
9.-12
Step-by-step explanation:
Answer: length = 30, breadth = 15
length = l
breadth = b
l = 2b
2b + b + 2b + b = 90
6b = 90
b = 15
l = 2b
l = 2(15)
length = 30
b = 15
breadth = 15
Y^2+5y the greatest common factor is y so
y(y+5)
...
4x^2-49 this is a "difference of perfect squares" which always factors to:
(a^2-b^2)=(a-b)(a+b), in this case:
(2x-7)(2x+7)
...
5s^2-20 GCF is 5
5(s^2-4) now the parenthetic term is a difference of squares so
5(s-2)(s+2)
