What is the gcf of 24and 16

8

Step-by-step explanation:

24 = 2×2×2×3

16 = 2×2×2×2

when finding gcf, we're multiplying the numbers that are equal for both of them

gcf(24;16) - 2×2×2 = 8

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
