Answer:
-2x^2+18
Explanation:
Since (x-0)^2 is the same thing as (x-0)(x-0), you should multiply out (x-0)^2, you’ll get this
-2(x^2-0x-0x+0)+18
Then simplify
-2(x^2)+18
-2x^2+18

A publisher estimates their costs of publishing a book is from $780,000 to $1,040,000. So far, they have spent $624,000. Which c

natulia [17]

The correct answer is:

156,000 ≤ x ≤ 416,000

Explanation:

The amounts they can spend range from 780,000 to 1,040,000. They have already spent 624,000 and have an unknown amount left to spend. This gives us the inequality

780,000 ≤ 624,000 + x ≤ 1,040,000

To solve this, subtract 624,000 from all 3 sides:

780,000-624,000 ≤ 624000+x-624,000 ≤ 1,040,000-624,000

156,000 ≤ x ≤ 416,000
