Step-by-step explanation:

7(4x + 9) - 4

= (7 × 4x) + (7 × 9) - 4

= 28x + 63 - 4

= 28x + 59

So, 7(4x + 9) - 4 is equivalent to 28x + 59 (D)

Hope it helpful and useful :)

Answer:

The answer is D

Step-by-step explanation:

Firstly, you have to get rid of brackets by expanding :

$7(4x + 9) - 4$

$= 7(4x) + 7(9) - 4$

$= 28x + 63 - 4$

Next you have to simplify :

$28x + 63 - 4$

$= 28x + 59$

Evaluate the following expression: p/-3 + (-8)= -8

aalyn [17]

P/-3+(-8)=-8
p/-3-8=-8
Add 8 to each side
p/-3-8+8=-8+8
p/-3=0
Multiply both side by 3
p/-3(3)=0(3)
p=0
Check:
p/-3+(-8)=-8
Substitute p with 0
0/-3+(-8)=-8
0-8=-8
-8=-8. As a result, p=0. Hope it help!
