3):   3.25  Multiply by 175  ======>  $568.75, Letter Choice, (C), is your final answer.

                            (3.25)(175)

=====>      Answer  568.75,   Letter Choice, (C).      



1):   Let's solve your equation step-by-step.

p     =      (2)(48)     +      (2)(6)

Step 1: Simplify both sides of the equation.

p      =      (2)(48)     +      (2)(6)

p       =     96     +     12

p      =     (96      +     12)       (Combine Like Terms)

p      =       108

p      =      108

Answer:     ======>    p     =     108,   Your Answer would be TRUE



2):    Modulus / Stress: N/mm2 ( =  MPa)

Equation:   ===>   S   =   7.2(8)2  + 3480

Let's solve your equation step-by-step.

s     =      (7.2)(8)(2)     +     3480

Step 1: Simplify both sides of the equation.

s      =      (7.2)(8)(2)      +      3480

s      =       115.2      +      3480

s       =       (115.2       +   3480)         (Combine Like Terms)

s      =       3595.20

s       =       3595.20  

Answer:    ======>   S     =    3595.20   Pascals Letter Choice, (C); is your answer.


Answers:

1):   TRUE  =====>   P   =====>   108

2):  Letter Choice, (C);  S    ======>  3595.20  PASCALS

3):    Letter Choice, (C);   $568.75
