Hope this helped
you mean 3x(4-8y)=3(2xy-5x)?
This is easy since you are already given the binomials. Just multiply them together.
(3x + 3)(3x + 3)
9x^2 + 9x + 9x + 9
9x^2 + 18x + 9.
The coefficient of term b is 18, so B = 18
The perimeter of shape B would be 60cm as well because they both have 5 squares.
1+tan^2=sec^2
so, given expression=
(using sin/cos=tan and tan*cot=1)
hence proved
