Answer:
You simply just do 12 multiplied by 10 which will give you 120m^2
Do (10 x 10) then (10 x 20), and then add your two answers together.
Its simple :)
Suppose that the value of other ratio is equal to 6/3 then,
20/3x-8 = 6/3
18x-48 = 60
18x = 60+48
18x = 108
x = 6
<span>twice the sum of a number and seven is 8
2(x+7)=8</span>
The value of x is 4. The steps to solving the equation are to use distributive property first so that the equation then looks like this: 10x+20=5x+40
Next you would combine like terms and then the equation would look like this: 5x+20=40
Then you would use the subtraction property of equality to subtract 20 from 40 so your equation will now look like this: 5x=20
Then you use the division property of equality to divide 20 by 5 to get x=4
