Answer:
Step-by-step explanation:
Negative sign is outside the parenthesis. So, each term of (4k² - 13k -12) should be multiplied by (-1)
-(4k² - 13k -12) + 5k² - 8k = 4k²*(-1) - 13k*(-1) - 12*(-1) + 5k² - 8k
= -4k² + 13k + 12 +5k² - 8k
Combine like terms,
= -4k² + 5k² + 13k - 8k + 12
= k² + 5k + 12
Like terms are the terms with same variable with same exponent.
(-4k² ) and 5k² are like terms
13k and (-8k) are like terms
Answer: finding volume is length times width times height and area is length times with so the ways they are the same are the fact that you do length times width for both and they fact that they are both solved through multiplication.
Step-by-step explanation: hope this helped :)
<u>Start from 7, then add 5 each time.</u>
a7 is 7 plus 30, or <u>37.</u>
No beacuse 19 1/2 is not bigger than 20
