The length of that semi circle is 6pi. So the perimeter should be 6pi + 24
Assuming the logarithm is base
, you have
Answer:
4x.
Step-by-step explanation:
If the scale factor is 2 then the area factor is 2^2 = 4.
So the area of the new triangle is 4*x.
Answer = 5(x+1)^2 -21
5 {x^2 + 2x } - 16
5 {(x+1)^2 -1 } - 16
5(x+1)^2 -5 - 16
5(x+1)^2 -21
