Let g(x) =2x and h(x) =x-2 find (g-h) (-4)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

good luck on ur quiz test or homework. have a good day : )
