Which expression is equivalent to 10x²y + 25x^2
r-ruslan [8.4K]

Answer:

5x²(2y + 5)

Step-by-step explanation:

10x²y + 25x²

to start we have to express the parts of the function as multiplication

2*5*x²*y + 5*5*x²

then we have to see that they have both parts of the sum in common, and what they have in common we get out of common invoice and what is left we add together.

5x²(2y + 5)

17 - 2n = 9 what’s the answer ?
BlackZzzverrR [31]

Step 1: Simplify both sides of the equation.

17−2n=9

17+−2n=9

−2n+17=9

Step 2: Subtract 17 from both sides.

−2n+17−17=9−17

−2n=−8

Step 3: Divide both sides by -2.

−2n−2=−8−2

n=4

Divide 3 and 1/6 /(-9)
ra1l [238]
If you would like to divide 3 and 1/6/(-9), you can do it using the following steps:

3 / 1/6/(-9) = 3/1  /  1/6/(-9) = 3/1 * (-9)/1/6 = -27 / 1/6 = -27 * 6 = -162

The result you get is -162.

Someone want to help me with some Geometry?
Aleks04 [339]
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.
