In order to do this, one side of the rectangle will be x+2, and the other will just be x. The x would be representing the width since the length is the width (x) plus two feet (+2). Next, you have to make an equation. So, since it all has to use 16 feet of fencing, you would set the two sides to be added to equal 16. So, it would be: 16=x+2+x. Then, you reduce that, so it would be: 16=2x+2. After that you just solve for x (which means that you want x by itself on one side of the = ). So, you would subtract 2 from both sides. Since 2-2=0, that would make the "+2" go away; since 16-2=14, that would replace the 16. So, your new equation is: 14=2x. After that you just divide both sides by 2 because 2 divided by 2=0. 14/2=7. So, you would end up getting: 7=x as your final answer.
Now, you just put 7 where x was in the sides. So 2x (which was the length) trims into: 2 times 7, which =14 and the x (which was the width) we already figured out was 7. This, the width would be 7, while the length would be 14.
Answer:
15 inches
Step-by-step explanation:
Call the original side length x
This makes the new length x+5
The perimeter is the sum of the length of the sides. So for the new shape this is 3(x+5)=60
This can be solved in the following way:
x+5=20
x=15
So the original side lengths were 15 inches.
Answer:
I think it’s the fist and the fourth
Step-by-step explanation:
Answer:
39 3/8
Step-by-step explanation:
The plant will be 34 millimeters after 8 months and 118 millimeters after 3 years. I solved this using the formula y=10+3x, where you are solving for y. You would replace x with the number of months and then solve.
