So first, this is point slope form. The first step is to distribute.)

Then add 4 to both sides.

Then add 2x and it becomes
Answer:
$16.60
Step-by-step explanation:
2.5x + 1.25(x - .20) = 31.25
2.5x + 1.25x - .25 = 31.25
3.75x - .25 = 31.25
3.75x = 31.25 + .25
3.75x/3.75 = 31.50/3.75
x = 8.40
y = x - .20
y = 8.20
1x + 1y = 16.60
Answer:
163.35
Step-by-step explanation:
13.5 x 12.1 = 163.35
Answer:
<u><em>x=9</em></u>.
<em><u>perimeter=68</u></em>
<em><u>area=168</u></em>
Step-by-step explanation:
First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to multiply the length and the width so 28x6 which is <em><u>168</u></em>.
