The area of a rectangular computer screen is 4x^2+20x+16. The width of the screen is 2x+8. What is the length of the screen?

1 answer:

7 0

So the area of a rectangle is Length x Width.
A = (L)(W)
Substitute the information given:
4x^2 + 20x + 16 = (L)(2x+8)
Isolate L by dividing 2x+8:
(4x^2 + 20x +16)/ (2x + 8) = L
If you divide:
L = 2x + 2.

Ian and April wish to have 8,000 available for the wedding in six years how much money should be set aside now at 6% compounded

ira [324]

Answer:

$\$5,586.42$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=6\ years\\ A=\$8,000\\ r=0.06\\n=12$

substitute in the formula above

$8,000=P(1+\frac{0.06}{12})^{12*6}$

$8,000=P(1.005)^{72}$

$P=8,000/(1.005)^{72}$

$P=\$5,586.42$
