Answer:
Area = length * width
112 = (2w+2)*w
112 = 2w^2 + 2w
0 =2w^2 + 2w - 112
0 = w^2 + w - 56
0 = ( w + 8 )( w - 7 )
w+8=0 results in negative measures
w-7=0 --> w = 7
width is 7
length is 16
Answer:

Step-by-step explanation:
Answer:
<h2>
50</h2>
Step-by-step explanation:
<h3>
40: 80x100 =</h3><h3>
100 =(40x100): 80 =</h3><h3>
100): 80 =4000: 80 = 50</h3>
The formula of the Simple Interest is:
I=PRT
P for Principle Amount ($1200)
R for Rate (5%=

= 0.05)
T for Time in years (4 years)
I = 1200 × 0.05 × 4
= $240
Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
