Use the power-reducing formulas to rewrite each of the expressions in terms of the first power of the cosine. sin^2x cos^4 x

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
