D. - 3k² – 2k+7 + K-2

Mathematics
1 answer:
11Alexandr11 [23.1K]3 years ago
8 0

Answer:

 3k2 - k + 5

just add all of the variables or minus all of the variables and if u can add the non-variable numbers but if a variable has exponent add it with the <u>same </u>type of variable exponent so in this case 3k squared doesn't get added to anything so it just stays 3k2 and -2k gets added to k which equals -k cause -2k is bigger than k and if the bigger number is negative in any equation stays negative. Then u just add all the numbers which would be 7+-2 which would equal five.

Hope this helped

Find the new amount 2000 miles increased by 33%
Goryan [66]

Answer:

2,660\ miles

Step-by-step explanation:

we know that

The amount of 2,000 miles represent 100%

If the amount is increased by 33%

then

The new percent of the amount will be

100%+33%=133%

so

using proportion

\frac{2,000}{100\%}=\frac{x}{133\%}\\\\x=2,000(133)/100\\\\x=2,660\ miles
