First, substitute the values of the variables into the equation:

2x+(3)(6)=36

Then, you must simplify,

2x+18=36

Then, you must factor out 18 to leave x and its coefficient alone on one side of the equation:

2x+18-18=36-18

Then you must simplify the equation and divide by 2 on both sides of the equation to factor out the coefficient:

2x/2=18/2

Then you will simplify and you will find the value of x:

x=9

3X6=18 and 36-18=18 and 18 divided by 2 is 9 so it is 9

if a rectangle has an area of 30 square meters and a perimeter of 34 meters . what is the dimensions of the rectangle?
timama [110]
P=2(L+W)  and P=34 so

2(L+W)=34

L+W=17 so we can say

L=17-W

A=LW using L from above

A=(17-W)W

A=17W-W^2 and A=30 so

30=17W-W^2

W^2-17W+30=0

W^2-2W-15W+30=0

W(W-2)-15(W-2)=0

(W-15)(W-2)=0

So the dimensions of the rectangle are 15 meters by 2 meters.
