Alright! When you have a constant to a power times another constant to a power (ex. [x^3 times x^3] ) you simply add the powers and keep the base [x^6]. When you have a power to a power (ex. [(12^3)^3] ) you multiply the powers and keep the base [12^9]. When you have a constant to a power divided by a constant to a power (ex. [ x^2 divided by x^5] ) you subtract the powers and keep the base. It's hard to see the questions, so I'll leave this here for you to use as a guide.

You are making identical gift bags using 12 crayons and 28 bottles of bubbles. What is the greatest number of gift bags you can

const2013 [10]

Since you don't want any leftover items, you have to find the greatest common factor (GCF) of both the crayons and bubbles. Since the highest common factor for both 28 and 12 is 4, the greatest number of gift bags you can make without any leftover items would be 4 gift bags.

Hope I could help.

If x=4 is a root, what is the corresponding factor?

Airida [17]

Answer:

(x - 4)

Step-by-step explanation:

Given x = a is a root then (x - a) is the corresponding factor

Given x = 4 is a root, then

(x - 4) ← is the corresponding factor

Note if x = - 4 is a root , then

(x - (- 4)), that is (x + 4) is the corresponding factor

What is the area of this figure?

Ugo [173]

Answer:

11610

Step-by-step explanation:

First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.

Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.

Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.

Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.
