Answer:
1. 4y-12
2. c
For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.
For #2 you factor out the 3 and you get 3(5x+1)
Answer:
slader app helps alot
Step-by-step explanation:
The answer is B (Sorry for the bad handwriting.)
1a. 3^1 / 3^2 = 3^1-2 = 3^-1 = 1/3^1 = 1/3.
2b. 4^2 / 4^4 = 4^2-4 = 4^-2 = 1/4^2.
3c. 6^3/6^5 = 6^3-5 = 6^-2 = 1/6^2.
4d. 3^-5 • 3^2 = 3^-10 = 1/3^10.
I believe for the last question its asking only to rewrite exponent as a positive exponent similar to the first question.
You just need to break it into parts. The first rectangle is the tall one. To find the area of this one, just multiply the tall side by the short side on top.
8 x 2 = 16
The second rectangle is the long one on the bottom. If the whole bottom side is 5 units, then you need to subtract 2 from that.
3 x 1 = 3
16 + 3 = 19 units, so the area of the entire shape would be 19 units^2. Hope this helps! :)
