Answer: The area of the banner is 100 in^2

Step-by-step explanation:

so let say the banner was still a rectangle with the triangle still attached to it so if we needed to find the area of the whole rectangle we will need to multiply the length times the width

so 14 * 8 = 112

But now a triangle is being cut out of the rectangle so we need to find the area of the triangle being cut out and subtract it from the area of the whole rectangle. But first we need to find the base and the base is 8 since the other side base is 8 too and the height will be 3 since 14- 11= 3

Now find the area of the triangle by multiplying the base times the height and divide it by 2.

8 * 3= 24

24/2= 12

subtract 12 from 112

112- 12 = 100

You and two friends rent a hotel room that costs $30 so you both put in $10 each later that night the owner of the hotel realize

Gennadij [26K]

The dollar didn't go anywhere! The question isn't correct because the money the bellhop stole is supposed to be subtracted, not added. So if we subtract $2 we have $25, and that's how much money the owner got, the men got $3 back and the bellboy got $2.

So the owner gets $25, the men get $3 and the bellboy gets $2, and that equals 30.

The area of a rectangle increased by seven is the same as for less than twice the area of the rectangle. Right and solve an equa

never [62]

Answer:

11 Square Units

Step-by-step explanation:

Let A be the area of the Rectangle

First statement: The area of the rectangle is increased by seven, we have :

A+7

Second Statement: Four less than twice the area of the rectangle

Twice the Area=2A

Four less = 2A-4

Therefore:

2A-4=A+7

Collecting like terms

2A-A =7+4

A=11

The area of the rectangle is 11 Square Units.
