Answer:
<u>6b - 4a + 22 units</u>
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(3b - 4a + 5 + 6 + 2a)
= 2(3b - 2a + 11)
= <u>6b - 4a + 22 units</u>
Answer:
$3400 after one year
$17400 after the 36 months
Step-by-step explanation:
3000+400*1=3400
3000+400*36=17400
Answer:
329, and sure!
Step-by-step explanation:
Answer:
Let l be length and w be width.
First equation:
l = 2w-4
Second equation:
perimeter = 40 units
Perimeter of a rectangle: 2(l+w)
2(2w-4+w)=40
2(3w-4)=40
6w-8=40
6w=40+8
6w=48
w=48/6
w=8
Therefore the width=8;
length= 2w-4 = 2(8)-4 = 16-4 = 12
perimeter = 40 units
1510 / 2302 = 0.6559 = 65.59%.....not sure if u need that rounded
