Dalila earns $108.75 for workin 15 hours as a holiday helper wrapping gifts. At this rate,how much money will she earn if she wo
Elden [556K]
Your answer would be $130.50.

We can write a ratio of earnings to hours as 108.75:15. Then, to find 18 hours, we find 1 hour and multiply by 18:

108.75 : 15
÷ 15
7.25 : 1
× 18
130.5 : 18

So therefore your answer is $130.50, I hope this helps!

Vinil7 [7]
The length can be 18 and the width can be 2.
18 x 2 = 36
Or the length can be 12 and the width can be 3.
12 x 3 = 36
The length can also be 9 and the width can be 4.
9 x 4 = 36

Answers:

5) product is 35ax^2 - 42axy + 7y^2

6) product is -a^6b^2 - 8a^5b - 5a^4

7) product is 12x^5y + 6x^4y^2 + 21x^3y^3

8) product is 3x^3y^2 - 6x^3y + 3x^5y - 3x^4y

9) product is x^{3n} + 7x^{n+1} - 3x^n

=============================================

Explanation:

For each of these questions, you'll multiply the term outside by each term inside the parenthesis. I'm using the distributive property.

In problem 5, we multiply the outer 7a by the following terms inside like so

7a(5x^2-2xy+y^2-4xy)\\\\7a(5x^2-6xy+y^2)\\\\7a(5x^2)+7a(-6xy)+7a(y^2)\\\\35ax^2-42axy+7ay^2\\\\

The other problems will have similar steps.

--------

A useful rule to keep in mind is that a^b*a^c = a^{b+c}

For example, x^2*x^3 = x^{2+3} = x^5
