Justin weighs 15 pounds less than Greg weighs. Half of Greg's weight is 75 pounds less than Justin's weight. How much does each of them
weigh?*
A-Greg weighs 180 pounds, and Justin weighs 165 pounds.
B-Greg weighs 170 pounds, and Justin weighs 155 pounds.
C-Greg weighs 200 pounds, and Justin weighs 185 pounds.
D-Greg weighs 190 pounds, and Justin weighs 175 pounds.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
