Answer:

2(y^2+17)

Step-by-step explanation:

First, add 13 and 21 together.

You'll end up with 2y^2+34

Then, factor out the two from each term, to get 2(y^2+17).

Since you can factor nothing else out, that will be your answer.

Answer:

4 feet of wall should be on each side of the painting.

Step-by-step explanation:

Given that a 4 foot wide painting should be centered on a 12 foot wide wall, to determine how many feet (X) should be on each side of the painting, the following equation must be solved:

(Total wide of the wall - wide of the painting) / 2 = X

(12 - 4) / 2 = X

8/2 = X

4 = X

Therefore, 4 feet of wall should be on each side of the painting.

A florist had 88 flowers. She wanted to put
EastWind [94]

Answer:

2 (Remainder 4) In decimal form to the hundredths: 2.09

Step-by-step explanation:

<h3>42 can only go into 88 two times, so 42 x 2 = 84. So then 2 is your answer. BUT you have 4 left, so it's 2 remainder 4. If you want to round to the tenths, hundredths, ect, here is the original decimated number: 2.09523809524</h3>

Can I get some help abs an easy explanation pls
Svetlanka [38]

we are given the following triangles:

We are asked to determine the value of "y". To do that we will use the tangent of 25:

\tan 25=\frac{y}{x}

We solve for "y" by multiplying both sides by "x":

x\tan 25=y

Now, we take the tangent of 15:

\tan 15=\frac{y}{30+x}

Now, we solve for "y" by multiplying both sides by the denominator:

(30+x)\tan 15=y

Now, we set both values of "y" equal, we get:

x\tan 25=(30+x)\tan 15

now, we solve for "x". First, we apply the distributive property on the right side:

x\tan 25=30\tan 15+x\tan 15

Now, we substract
