Answer: false
Step-by-step explanation:
The exponents would have to have a different sign from each other (positive or negative), not the integer.
It would be 15 because the way you would set it up is equal to 180 because they are opposite and they have to add up to 180 in order for the whole shape to be 360. so 3x+9x=180 and then 12x=180 and divide 180 by 12 which is 15 and you can also plug in 15 to check
Answer:
87 feet
Step-by-step explanation:
Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:
30+9+12+9+9+9+9=87 feet
Hope this helps!
Answer:
r ≥ -1. it is A because r is greater than or equal to -1.
I am sorry <u>if</u> I got it wrong.
Step-by-step explanation:
3r+2(12r+7) ≤ 5r-8
27r+14 ≤ 5r-8
I subtract 27r and 5r.
22r+14 ≤ -8
I subtract 14 and -8.
22r ≤ -22
Divide 22 on both side.
r ≥ -1
