Let the width of the rectangle be x. Then the length would be x+2
Area=(length)*(width)
48=x(x+2), => x=6. Width is 6 and length is 8
Answer:
D.
Step-by-step explanation:
the starting number is 370 and it gets multiplied by 1.11 every year so you would root the equation by t
Let us denote the years of Mary with M and the years that Al have with A.
<span>We know that the sum of Mary and Al's age is 48. So, we can write:
M+A=48 (1)
</span><span>We also know that twelve years ago, Mary was twice as old as Al.
So we can write:
M-12=2*A (2)
From the first equation (1): M=48-A
Let put this in the second equation:
48-A-12=2A
36=3A
A=12
M=48-12=36

Since all of the side lengths are different, it is a scalene triangle
