Solve the expression: [(3.2)² - (-4)³ ] [(75/15) - (-10 + 15)] + (-19/3)?

Solve the expression: [(3.2)² - (-4)³ ] [(75/15) - (-10 + 15)] + (-19/3)?

• A. -543.93
• B. -6.33
• C. -60.09
• D. 12.07

Answer: (B)

To solve the expression, we need to break it down step by step: 1. Calculate \( (3.2)² \): \[ (3.2)² = 10.24 \] 2. Calculate \( (-4)³ \): \[ (-4)³ = -64 \] 3. Now, simplify \( (3.2)² - (-4)³ \): \[ 10.24 - (-64) = 10.24 + 64 = 74.24 \] 4. Next, calculate \( \frac{75}{15} \): \[ \frac{75}{15} = 5 \] 5. Now simplify \( -10 + 15 \): \[ -10 + 15 = 5 \] 6. Then simplify \( 5 - (-10 + 15) \): \[ 5 - 5 = 0 \] 7. Now we have the full expression \( (74.24) \times (0) \): \[ 74.24 \times 0 = 0

To solve the expression, we need to break it down step by step:

1. Calculate ( (3.2)² ):

[

(3.2)² = 10.24

]

2. Calculate ( (-4)³ ):

[

(-4)³ = -64

]

3. Now, simplify ( (3.2)² - (-4)³ ):

[

10.24 - (-64) = 10.24 + 64 = 74.24

]

4. Next, calculate ( \frac{75}{15} ):

[

\frac{75}{15} = 5

]

5. Now simplify ( -10 + 15 ):

[

-10 + 15 = 5

]

6. Then simplify ( 5 - (-10 + 15) ):

[

5 - 5 = 0

]

7. Now we have the full expression ( (74.24) \times (0) ):

[

74.24 \times 0 = 0
