Let's draw a diagram of this room so it's easier to solve. (see the image I've included)
The perimeter is the length of all of the sides of the rectangle, so
8 + 8 + x + x = 40
Simplify
16 + 2x = 40
Subtract 16 from both sides
2x = 24
Divide by 2 on both sides
x = 12
The length of the rectangle is
12.
Hopefully this helps! If you don't understand or have more questions, feel free to DM me!! :)
Answer:
total cost of her loan be if she paid it off 8 years early $389,507.11
Step-by-step explanation:
The formula for annual compound interest, including principal sum P, rate of interest r, number of years t, and the number of times that interest is compounded per year is n:
A = P (1 + r/n)^ (nt)
<u>calculate total cost after 22 years</u>
P = $145,000
r = 4.5 %
t = 22 years
n = 12
A = P (1 + r/n)^ (nt)
A = 145,000(1 + 4.5/12)^ (22x12)
A = $389,507.11
Answer:
b
Step-by-step explanation:
because the sum of two opposite interior angle is equal to the exterior angle
if one angle is 11 and the other one is 3
then the sum is 14
so the right answer is b
So because the factors of the equation are (x-2), (x+3) and (x-3), you set them equal to zero and you get x=2, -3, and 3
1) 2x + 3y = 12 -> 3y = -2x +12 -> y = -2/3x + 4
2) 4y - 7x = 16 -> 4y = 7x + 16 -> y = 7/4x + 4
