Question

PLEASE ANSWER QUICKLY I WILL GIVE BRAINLYEST

Answer 1

Answer:

a) 17

b) 45

Step-by-step explanation:

a) $9+3 x 2^{2} - 1 x 4$

use pemdas first,

$2^{2}$ = 4

3x4 = 12

1x4 = 4

now the equation is $9+12 - 4$

9+12 = 21

that makes the equation 21-4

21-4 = 17

a) 17

now for b

b)

the equation would then be $9+3 x (2^{2} - 1) x 4$

so youd use pemdas as always

start in the parenthases

$2^{2}$ = 4

4-1 = 3

the equation is now $9+3 x 3 x 4$

now, multiply 3x3x4

3x3 = 9

9x4 = 36

now the equation is 9+36

9+36 is 45

b) 45

hope this helped!
