Find the values for c and d that would make the following equation true. (cy^2)(4y^d)=-20y^3

c = -5 and d = 1

Step-by-step explanation:

First, multiply out (cy^2)(4y^d).  We get:  4cy^(2+d).

We equate this result to the right side of the equation:  - 20y^3.

Then, equating the exponents and solving for d, we get:  2 + d = 3, or d = 1.

Equating the coefficients, we get 4c = -20, or c = -5.

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
