= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:

= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14

In short, Your Answer would be: 15u³ + 8u² - 3u + 14

Hope this helps!

Kellogg's produced 715000 boxes of cornflakes this year. This was 110% of annual production last year. What was last year's annu

Charra [1.4K]

Let last year product be x boxes.

110% of x means $\displaystyle{ \frac{110}{100}\cdot x$ .

Thus, we solve the equation:

$\displaystyle{ \frac{110}{100}\cdot x=715,000$ .

Multiplying both sides by $\displaystyle{ \frac{100}{110}$ , we have:

$\displaystyle{ x=715,000 \cdot \frac{100}{110}=650,000$ .

Answer: Last <span>year's annual production was 650,000 boxes.</span>
