Subtract 43 from 20 raised to the 7th power; then multiply by 3.

Hi there! :)

Answer:

Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: 3,839,999,871

Step-by-step explanation:

"Subtract" means to take away a number from another.

" 20 raised to the 7th power" is the same thing as 20 exponent 7: $20^{7}$

SO, you want to take away 43 from $20^{7}$ and then multiply the answer by 3:

( $20^{7}$ - 43) × 3

$20^{7} =$ 1,280,000,000

(1,280,000,000 - 43) × 3

1,280,000,000 - 43 = 1,279,999,957

1,279,999,957 × 3

1,279,999,957 × 3 = 3,839,999,871

There you go! I really hope this helped, if there's anything just let me know! :)

Answer:

B. -x + 8

Step-by-step explanation:

Given expression

$\dfrac{8-4(x-6)}{4}$

Consider the numerator $8-4(x-6).$

First, use distributive property:

$8-4(x-6)=8-(4x-24)$

Open the brackets:

$8-(4x-24)=8-4x+24$

Combine the like terms:

$8-4x+24=(8+24)-4x=32-4x$

Again use distributive property:

$32-4x=4\cdot 8-4x=4(8-x)$

Now, the expression is

$\dfrac{4(8-x)}{4}=8-x\ \text{or}\ -x+8$
