Answer:

150

Step-by-step explanation:

Substitute the given values for a, b and c into the expression

- (- 4)² + 7(-2)^{4} - 2(-3)^{3}

= - 16 + (7 × 16) -2(27)

= - 16 + 112 + 54

Use the distributive property to evaluate each expression <br> 4(8-7), 4(x-6y), 6(5-q), (d+2)(-7)
Whitepunk [10]

Answer:

Rewrite the expression 10(15 – 6) using the distributive property of subtraction.

A) 10(6) – 10(15)

B) 10(9)

C) 10(6 –15)

D) 10(15) – 10(6)

Show/Hide Answer

A) 10(6) – 10(15)

Incorrect. Here a greater number would be subtracted from a lesser number, and the answer would not be a whole number. The correct answer is 10(15) – 10(6).

B) 10(9)

Incorrect. The numbers in parentheses were subtracted before the number 10 could be distributed. The correct answer is 10(15) – 10(6).

C) 10(6 –15)

Incorrect. You probably used the commutative law instead of the distributive property. The correct answer is 10(15) – 10(6).

D) 10(15) – 10(6)

Correct. The 10 is correctly distributed so that it is used to multiply the 15 and the 6 separately.
