5) Perimeter equals all the sides, and a rectangle has two pairs of equal length sides. If one side is 10 and the other is n, the perimeter would be 2n+20.
Area equals length times width, in this case 10 times n, which just equals 10n.

We can use the same logic for 6.
(7)+(7)+(y+2)+(y+2) = 2y+18 for the perimeter

You just have to use the distributive property to find the area, but it’s still length times width.

7(y+2) = 7y + 14.


Tl;dr
5: 2n+20 and 10n
6: 2y+18 and 7y+14

Hope this helps!

The difference between of two numbers is 9. If the large number is one more than twice the smaller number, find the larger numbe
sleet_krkn [62]

The larger number is 17

<em><u>Solution:</u></em>

Let "x" be the larger number

Let "y" be the smaller number

<em><u>The difference between of two numbers is 9</u></em>

Therefore,

larger number - smaller number = 9

x - y = 9 -------- eqn 1

<em><u>The large number is one more than twice the smaller number</u></em>

Larger number = 1 + 2(smaller number)

x = 1 + 2y ------ eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

<em><u>Substitute eqn 2 in eqn 1</u></em>

1 + 2y - y = 9

1 + y = 9

y = 9 - 1

y = 8

<em><u>Substitute y = 8 in eqn 1</u></em>

x - 8 = 9

x = 8 + 9

x = 17

Thus the larger number is 17
