Can someone explain what i did wrong?

56

Step-by-step explanation:

Since A is 4 and C is -3, you have to follow PEMDAS or (whatever it's called) and do exponents first. -3^2 is 9, and 4*9 is 36. since B is 5, 5*4 is 20, and 36+20 is 56 I think

-16

Step-by-step explanation:

a= 4

b= 5

c= -3

ac² + ab   plug in values:

= 4 * -3² + 4 * 5   follow the PEMDAS order of operations

= 4(-9) + 4 * 5

= -36 + 4 * 5

= -36 + 20

= -16

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
