Answer: x=3 units. Perimeter:22 units

Step-by-step explanation:

P=perimeter

3x-1=2x+2

x-1=2

x=3 units

P=3x-1+2x+2+2x

P=3(3)-1+2(3)+2+2(3)

P=9-1+6+2+6

P=8+8+6

P=22 units

Multiple the sum of a number and 3 by the difference of 8 and the number

Whitepunk [10]

Answer:

-n^2 - 5n + 24

Step-by-step explanation:

Let the number be n.

Then the sum of that number and 3 is n+3.

The difference of 8 and the number is 8 - n.

Then we get the expression (n + 3)(8 - n).

Performing the indicated multiplication, we get:

8n - n^2 + 24 - 3n, or

-n^2 - 5n + 24

Nothing more can be done, as this is not an equation, but rather an expression.

You are the administrator of an annual essay contest scholarship fund. This year a $80,000 college scholarship is being divided

Hatshy [7]

Answer:

Runner Up Amount=$16,000

Winner Amount=$64,000

Step-by-step explanation:

Amount of the college's scholarship=$80,000

The fund is being divided between the top two contestants so that the winner receives four times as much as the runner-up.

Therefore: we can say it is being divided into 5 parts where the winner gets 4 parts and the runner up gets 1 part, i.e in the ratio 4:1.

Runner Up Amount $=\dfrac{1}{5}X\$ $80,000=\$16000$

Winner Amount $=\dfrac{4}{5}X\$ $80,000=\$64000$

The winner gets $64,000 and the runner up gets $16,000.
