Answer:
correct
Step-by-step explanation:
The perimeter is the sum of the sides.
Rectangle ( opposite sides are congruent ), thus
perimeter = 2x + 2(x + 18) = 2x + 2x + 36 = 4x + 36
Square ( sides are congruent ), thus
perimeter = 4(x + 9) = 4x + 36
The perimeters are the same, so the student is correct
Answer is 26+15i
(2-7i) x (-1+4i)
-2+2x4i-7i ( -1) -7i+4i
-2+8i+7i-28i^2
-2+8i+7i-28(-1)
-2+8i+7i+28
26+ 15i
