Answer:

7) (f+g) (x) = 4^x + 5x -5

8) (f-g) (x) = 4^x + x - 5

Step-by-step explanation:

7) Find (f +g)(x)

(4^x + 3x + 2x - 5)

(4^x + 5x -5)

(f+g) (x) = 4^x + 5x -5

8) Find (f-g)(x)

(4^x + 3x - 2x - 5)

(4^x + x - 5)

(f-g) (x) = 4^x + x - 5

The perimeter of a stop sign is 99.2 inches. Each side of the stop sign is equal.

san4es73 [151]

Answer: The equation can be written as 8n = 99.2.

Step-by-step explanation:

In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.

A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.

Hence, the answer can be represented as 8n = 99.2.

4 1/2 times 5 2/3 plz!!!!!!! Help!!!!!!!!!

Over [174]

Answer:

25 1/2

Step-by-step explanation:

Turn both numbers into a fraction.

4x2=8

8+1=9

9/2 x 5 2/3

5x3=15

15 + 2 = 17

9/2 x 17/3

Make the denominator the same

2x3=6

9x3=27

27/6

17x2=34

27/6 x 34/6

Multiply numerator w numerator and denominator w denominator

27 x 34 = 918

6 x 6 = 36

918/36

Break it down

36 x 26 = 936

936-918=18

25 18/36

18/2 36/2 = 9/18

9/9 18/9= 1/2

25 1/2
