To simplify 4/(2+7i), we multiply it by a fraction equal to one that removes the i value in the denominator. The best value to do this is the complex conjugate divided by itself, so we have 4(2-7i)/((2+7i)(2-7i)). Simplifying, we have (8-28i)/(4-(-49))=(8-28i)/53, which is a completely simplified fraction since 8 and 53 are relatively prime (or coprime), and there are no radicals in the denominator.
The sum oh p 3/4 should be 3.333

Answer:
759 square foot garden
Step-by-step explanation:
L= length
W= Width
Perimeter = 2(L + W)
112 = 2(L + W)
divide both sides by 2 and you get
56 = L + W
L=33
W=23
