Answer:

\frac{x+xy}{y}

Step-by-step explanation:

Given

\frac{x}{y} + x

Multiply x by \frac{y}{y} to create a common denominator

= \frac{x}{y} + x × \frac{y}{y}

= \frac{x}{y} + \frac{xy}{y}

= \frac{x+xy}{y}

I need help with this? <br> i’m so confused
Sever21 [200]

Answer:

See below

Step-by-step explanation:

In #4, the angles are vertical because the angles are congruent to each other. Therefore, you would set up the equation x+8=120 where x=112.

In #5, the angles are complementary because their sum is 90°. Therefore, you would set up the equation 43+x+3=90 where x=44.

In #6, the angles are supplementary because their sum is 180°. Therefore, you would set up the equation 76+2x+4=180 where x=50.

Please answer math questionS correctly for BRAINY
agasfer [191]
Hello there,

1st attachment: 

So in order to find this answer. We need to know that in a CUBE there is L*W*H. Your answer would be A.) 1125 because when we do 1125 3 times (L*W*H). . . It give's us 3375.

2nd attachment:

Your answer would be D.) 5,832m³.

My reason I say this is because when you do 18 square root to 3. It will give you 5,832m³

3rd attachment:

Your correct answer would be 80mm³. So this is what I did. C wouldn't be the wrong answer because that answer is in "inches" and we want to find the answer in "mm³" So when we do 2*2*2. We get 8cm. We need to find the answer in "mm³" "8cm" converted in "mm³" would equal 80mm³.

Hope this helps.
