Express the area of the entire rectangle.

Cloud [144]

Answer:

$\huge\boxed{A=x^2+12x+35}$

Step-by-step explanation:

The formula of an area of a rectangle:

$A=lw$

l - length

w - width

We have

$l=x+7\\\\w=x+5$

Substitute:

$A=(x+7)(x+5)$

Use FOIL (a + b)(c + d) = ac + ad + bc + bd

$A=(x)(x)+(x)(5)+(7)(x)+(7)(5)\\\\A=x^2+5x+7x+35$

combine like terms

$A=x^2+(5x+7x)+35\\\\A=x^2+12x+35$

A 90-day simple interest loan in the amount of $2350 will be paid in full in the amount of $2500 . Find the rate of the loan.

ivolga24 [154]

Answer:

The rate of simple interest is 25.89 %

Step-by-step explanation:

Given as :

The principal = $2350

The Amount = $2500

The time period = 90 days = $\frac{90}{365}$ year = 0.2465 year

Let The rate of interest = R %

So, Interest = Amount - Principal

Or, Interest = $2500 - $2350 = $150

From Simple Interest method

Simple Interest = $\frac{Principal\times rate\times Time}{100}$

Or, $150 = $\frac{$2350\times rate\times 0.2465 }{100}$

or, $150 × 100 = $579.275 × Rate

So, Rate = $\frac{15000}{579.275}$

∴ Rate = 25.89 %

Hence The rate of simple interest is 25.89 % Answer
