Given :

→x-y=12

→xy= 3²

Equation formed:

${(x - y)}^{2} = {x}^{2} + {y}^{2} - 2xy$

Step by step explanation:

${(12)}^{2} = {x}^{2} + {y}^{2} - 2 \times 9 \\ 144 + 18 = {x}^{2} + {y}^{2} \\ = 162$

How to I find this? I tried using Pythagorean theorem, but it didn't work

jarptica [38.1K]

The Pythagorean theorem works.

$12^2+9^2=c^2$
$144+81=c^2$
$225=c^2$
$15=c$

Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)

If you deposit ₱10,000 into an account that earns 5% annual interest compounded semiannually, how long will it take until there

emmainna [20.7K]

Answer:

t = 3.69 ≈ 3. 7 years

Step-by-step explanation:

Given :

P = 10,000

r = 5%= 0.05

A = 12,000

n = 2 ( because it is compounded semi - annually )

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

$12000 = 10000(1 + \frac{0.05}{2})^{2 t}\\\\1.2 = ( 1 + \frac{0.05}{2})^{2t}\\\\1.2 = (1.025)^{2t}\\\\log \ 1.2 = 2t \ log \ 1.025\\\\2t = \frac{log 1.2 }{log 1.025} \\\\2t = \frac{0.1823}{0.0247}\\\\2t = 7.3805\\\\t = 3.69$

Help me write "5x-(x-18)= " in those things. 5(-7) <---- (Something like that)<br> X = -7

anzhelika [568]

Answer:

This how you get x. First the way to find the answer is to first put 5x by itself by canceling it out and putting it on the other side of the = which will be

5x-(x-18)=

-5x -5

Which then gets you this

-(x-18)=-5x

After that its

x-18=-5x

once you have this subtract x

x-18=-5x

-x -x

-18=-6x

Then it leaves you the easy part of just dividing

-18/-6x=-6x/-6x

After dividing you get x to be 3

x=3

Once you have x=3 input that number into your equation and you get the answer.

Hope this helps
