P = 2L + 2W ; for L step by step

vovikov84 [41]

Hi there!

Let's take this step by step. First, we'll divide both sides by 2. Doing this gives us P/2 = L + W. Next, we'll subtract W from both sides in order to isolate L. Doing this gives us L = P/2 - W.

Hope this helps!! :)

The sum of the squares of two positive integers is 394. If one integer is 2 less than the other and the larger integer is x. Fin

IgorLugansk [536]

Larger is x
the other is called y
sum of squares is 394
x^2+y^2=394
one is 2 less that other
x>y so
y+2=x
subsitute y+2 for x

(y+2)^2+y^2=394
expand
y^2+4y+4+y^2=394
add like terms
2y^2+4y+4=394
divideboth sides by 2
y^2+2y+2=197
subtract 197 from both sides
y^2+2y-195=0
factor
(y+15)(y-13)=0
set each to zero
y+15=0
y=-15
impossible since it is stated that they are positive so get rid of this solution
y-13=0
y=13

find other
y+2=x
13+2=x
15=x

numbers are 13 and 15

Trevor and $826 on account during 2.5% annual interest for seven years.

photoshop1234 [79]

Trevor invested $ 4720

<em><u>Solution:</u></em>

Given that, Trevor earned $ 826 on account during 2.5% annual interest for seven years

We can simple interest formula

<em><u>The formula for simple interest is given as:</u></em>

$\text{ Simple Interest } = \frac{p \times n \times r}{100}$

Where,

"p" is the principal

"n" is the number of years

"r" is the rate of interest

Here given that,

Principal = p = ?

rate of interest = r = 2.5 %

number of years = n = 7

Simple interest earned = 826

<em><u>Substituting the values in above formula,</u></em>

$826 = \frac{p \times 7 \times 2.5}{100}\\\\82600 = p \times 7 \times 2.5\\\\82600 = 17.5p\\\\p = \frac{82600}{17.5}\\\\p = 4720$

Thus he invested $ 4720
