The answer is -4.
You can refer to the handwritten answer for further understanding
A direct variation means that y=kx, where k is constant.
-12=k(-4)
3=k
Plug in the known y value
24=3x
8=x
Final answer: 8
8a² - 4b + 7a² and 5(3a² - 2b) + 6
First, simplify the expressions.
1) 8a² - 4b + 7a²
Add like terms.
15a² - 4b
2) 5(3a² - 2b) + 6
Distribute 5 by multiplying the number to each terms inside the parenthesis.
15a² - 10b + 6
15a² - 4b ≠ 15a² - 10b + 6
Solution: The expressions are not equivalent.
Answer:
134
Step-by-step explanation:
7 x 5 + <u>(3 x 5)</u> First do the parenthesis
<u>7 x 5</u> + 15 Next do multiplication (left to right)
<u>35 + 15 </u> Last add the two remaining numbers
50
