Answer:
The perimeter of the large rectangle is 75 feet.
Step-by-step explanation:
We know that the perimeter is the sum of all side lengths. It scales just as the sides themselves.
Given that the two perimeters scale as 2:3.
This means if the perimeter of the small rectangle is 50 feet, the perimeter of the large rectangle.
(3/2) × 50 = 3 × 50=75 feet.
Thus, the perimeter of the large rectangle is 75 feet.
2z+4=12
2(4)+4=12
<em>8+4=12</em>
____________
5z*2=40
5(4)*2=40
<em>20*2=40</em>
Answer:a=3/4
b=3/4
3a+5b=6
9a+7b=12
-3(3a+5b)=-3(6)
-9a-15b=-18
-8b=-6
3a+5(3/4)=6
3a+15/4=6
3a=9/4
a=3/4
it looks like an acute angle
