Answer:

(f+g)(x)=2x+1+5 - x

(f+g)(x)=x + 6

(f - g)(x)= 2x + 1 - (5- x )

(f - g)(x)= 3x - 4

The dimensions of four rectangles are given below. Which has an area different from the area of each of the other three?
storchak [24]

To determine which of the rectangles has a different area, the areas of the four rectangles must be calculated. The rectangle with a different area is rectangle b

The dimension of the 4 rectangles are:

a. length: 4x and width: 4

b. length: 11 and width: x

c. length: 2 and width: 8x

d. length: 16x and width: 1

The area of a rectangle is:

Area = Length \times Width

<u>Rectangle (a)</u>

Area = 4x \times 4

Area = 16x

<u>Rectangle (b)</u>

Area = 11 \times x

Area = 11x

<u>Rectangle (c)</u>

Area = 2 \times 8x

Area = 16x

<u>Rectangle (d)</u>

Area = 16x \times 1

Area = 16x

Rectangles (a), (c) and (d) have the same area (i.e. 16x) while rectangle (b) has 11x as its area.

Hence, the rectangle with a different area is rectangle (b).

Each of the students im Romi's class raised at least $25 during the jump-a-thon. What is the least amount of money the class rai
EastWind [94]
If each of the 28 students made at least $25, you would multiply 28 and 25 together to obtain the least amount of money the class raised. That gets, 28x25 = 700. The class made at least $700.
