Answer:

Step-by-step explanation:

Multiply both sides of the equation by 99, the least common multiple of 9,39,3.
m + 6 =21
Subtract 6 from both sides.
m = 21 - 6
Subtract 6 from 21 to get 15.
m=15
Answer:
<em>Width</em>: 3y²
<em>Length</em>: 4 + 7y³
Step-by-step explanation:
The area of the rectangle is the length multiplied by the width. For the area given: 12y² + 21y⁵
12y² = 3y²*4
21y⁵ = 3y²*7y³
So, the greatest common monomial factor is 3y², which is the width.
The area is 3y²*(4 + 7y³), the first term is the width, the other must be the length: 4 + 7y³.
First Column, -x and 5 third column, -x and 2
Answer:
13
Step-by-step explanation:
the difference is -5
- nth=a+(n-1)d
- a=253,n=49,d=5
- 253+(49-1)×-5
- 253+48×-5
- 253+(-240)
- 253-240=13
the 49th term is 13
