2x-4 D it can be your answer if you multiply correctly and you do it
8:5 because it’s girls to boys, and that’s the lowest you can simplify them
Angle α and β are supplementary angles and when added together equal 180.
Set up an equation:
α + β = 180
β = α +30
Replace β in the first equation, to get:
α + α +30 = 180
Simplify:
2α +30 = 180
Subtract 30 from both sides:
2α = 150
Divide both sides by 2:
α = 150 /2
α = 75 degrees.
Answer:−2x^3+8x^2−4x
Step-by-step explanation:
Equation:-2x(x2-4x+2)
=(−2x)(x^2+−4x+2)
=(−2x)(x^2)+(−2x)(−4x)+(−2x)(2)
=-2x^3+8x^2-4x
