A = l * w
66 = l * (l - 5)
66 =

-5l
0 =

-5l - 66
l = 11 or 6 check which works.
A = 11 * 6, which fits.
length = 11 miles
width = 5 miles
Step-by-step explanation:
1) Ans 3
2) Ans 6
3) Ans 4
4) Ans 1/5
5) Ans 1/23
I get w = 15. So Semir walked 15 miles and Sarah walked (2(15) - 5) miles, or 25 miles.
Distribute multiplication over addition and subtraction:
3x+ 12y+10x-5y
Combine like terms:
13 x +7y
Answer:
D) 7/2
Step-by-step explanation:
y=1/3 (ax-2) =>(2,3) so x=2, y=3.
Then,3=1/3 (2a-2)=> 9=2a-2 and a=7/2
So, slope is 7/2
