Answer:
Question 1: B = 0
Question 2: 23/2 or 11-1/2
Question 3: 663/6 or 110-3/6
Step-by-step explanation:
Question 1:
(-5²)+(9+4²)=5B
-25+9+16=5B
5B=-0
B=0/5=0
Question 2:
2-7/8×2-6/9×1-1/2
=23/8×24/9×3/2
=23/2
=11-1/2
Question3:
3-1/4×6-2/3×5-1/10
=13/4×20/3×51/10
=663/6
=110-3/6
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)
calculate total cost after 22 years
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:
Perimeter of the rectangle is 16x+18 units.
Step-by-step explanation:
The area of rectangle is
First we have to find the factor form of above expression.
Splitting the middle term, we get
Area of a rectangle is the product of its dimensions. It means dimensions of the rectangle are (x+8) and (7x+1).
Perimeter of a rectangle is
![Perimeter=2[(x+8)+(7x+1)]](https://tex.z-dn.net/?f=Perimeter%3D2%5B%28x%2B8%29%2B%287x%2B1%29%5D)
![Perimeter=2[8x+9]](https://tex.z-dn.net/?f=Perimeter%3D2%5B8x%2B9%5D)
Therefore, the perimeter of the rectangle is 16x+18 units.
