Answer:
The correct answer is D
Step-by-step explanation:
You can find the correct answer just by looking at what the first term would end up being.
The first three, if you expanded them, would all have the starting term 2x³, which does not match the result unless the two is factored out. Only the last one would end up with the correct x³ as its first term.
Let's expand it to see if we're right:
(x + 2)(x² + 3x + 5)
= x³ + 3x² + 5x + 2x² + 6x + 10
= x³ + 3x² + 11x + 10
And that's a match, so the correct answer is D
Answer:11/c
Step-by-step explanation:
Answer:
y = 90 -5/2 x
Step-by-step explanation:
The angle on the left equals x+3x+x = 5x
The angle on the right equals 2y
The two angles are same side interior angles which are supplementary because the lines are parallel
5x+2y = 180
Solving for y
2y = 180-5x
Divide by 2
2y/2 = 180/2 -5x/2
y = 90 -5/2 x
