Evaluate 6+2•3-1 a) 23 b)16 c)10 d)11

6 + 2 * 3 - 1

2 * 3 = 6

6 + 6 - 1

6 + 6 = 12

12 - 1 = 11

D) 11

D) 11

Step-by-step explanation:

If it helps, remember the order of opperations:

PEMDAS.

P = Parenthesis (you don't have any ( ) in this equation, so skip it.)

E = Exponents ( skip this step too. )

M = Multiply, (this is your first step.)

D = Divide

A = Add

S = Subtract

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
