Answer:
1200*(1 + 0.045*x) = 1500 --> x = 5.55 --> C. 6 years
A = P( 1 + r/n)^(nt)
A = 100(1 + .04/4)^12
A = 100(1.01)^12
A = 112.68
Answer:
width is 47 and the length is 90
Step-by-step explanation:
Hello!
You find the perimeter by adding all the sides
l + l + w + w = p
The perimeter is 274
l + l + w + w = 274
It says the length is 4 less than double the width
l = 2w - 4
We can put this into the original equation
2w - 4 + 2w - 4 + w + w = 274
Now we solve
Combine like terms
6w - 8 = 274
Add 8 to both sides
6w = 282
Divide both sides by 6
w = 47
We can put w into the orginal equation to find l
l + l + 47 + 47 = 274
Combine like terms
2l + 94 = 274
Subtract 94 from both sides
2l = 180
Divide both sides by 2
l = 90
The answer is the width is 47 and the length is 90
Hope this helps!
