Answer:
9,200
Step-by-step explanation:
72,300 - 63,100 = 9,200
Answer:
33.33%
Step-by-step explanation:
well answer choices would help so I know which percentage they want but a 150 increase from 450 to 600 is about 1/3 or 33.33% of 450 and is about 1/4 or 25% of 600 but based on the structure of the question im willing to wager they want 33.33% increase on 450 is 600
Answer:
j² - 5j²k - 2
Step-by-step explanation:
3j² - j²k - 6 - 4j²k - 2j² + 4
To simplify this polynomial, we can collect like terms. A term is number(s) or variable(s) that are grouped together by multiplication. <u>Like terms have the same variable and exponent</u>.
We have three groups of like terms:
The j-squares (j²), the j-squared k (j²k) and the constants (no variable).
Remember to include the negatives!
The j-squares are: 3j² ; -2j²
The j-squares k are: - j²k ; - 4j²k
The constants are: - 6 ; 4
Simplify:
3j² - j²k - 6 - 4j²k - 2j² + 4
Rearrange the polynomial by like terms
= (- j²k - 4j²k) + (3j² - 2j²) + (- 6 + 4)
Add or subtract the like terms
= (-5j²k) + (j²) + (-2)
Remove brackets and rearrange so the negative is not first
= j² + - 5j²k + - 2
Simplify where two signs are together. Adding a negative is subtraction.
= j² - 5j²k - 2 Simplified
Yes it is. "To the power of" just means you are multiply a number by itself how many times.
