Answer: z=-190
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Simplify 140/96 into 35/24 since they have the common factor 4. Then convert it to 1 whole and 11/24
W=2L
P=300=2(L+W)
so
300=2(L+W)
divide by 2
150=L+W
W=2L
subsitute
150=L+2L
150=3L
divide by 3
50=L
sub back
W=2L
W=2(50)
W=100
the field is 100yd wide by 50yd long
Answer:
see explanation
Step-by-step explanation:
Given
(a + bi)(a - bi) ← expand using FOIL
= a² - abi + abi - b²i² → i² = - 1
= a² + b²
Since a and b are any real numbers, then
a² + b² is a real number
B
When a complex number is multiplied by its conjugate the result is always real.
