Hi,
c=4, b=2, a²=b²+c²==> a=2√5
The formula is
a^3 - b^2 = (a - b)(a^2 + ab + b^2) so plugging in the given values:-
a = cube root of 125 = 5 and b = cube root of 27 = 3 , we get:-
125 - 27 = (5 - 3)(5^2 + 5*3 + 3^2)
= 2 * 49
= 98 answer
It’s B because the y intercept is +3
To find the lengths of the enlarged triangle, we would find the scale factor from the given length
22.5/5 = 4.5
So to find the other sides you would multiply 3 and 6 by 4.5
3 * 4.5 = 13.5
6 * 4.5 = 27
So all 3 lengths of the triangle are 22.5, 13.5, and 27
To find the perimeter you add all
22.5 + 13.5 + 27 = 63
Your answer is 63
I hope this helps good luck
