Answer:
C. 8x+80.
Step-by-step explanation:
To make this a simple expression, we need to distribute the 8 into x+10. We do this by multiplication. 8*x=8x. 8*10=80. Our new equation is 8x+80.
Answer:
Equivalent
Step-by-step explanation:
4:5 multiply both sides by 4 to get 16:20
The last two choices.
Supplementary and linear
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 8 from both sides
x + 8 (-8) = -2 (-8)
x = -2 - 8
Combine
x = -10
-10 is your answer for x

4y⁴ - 8y³ - (5y³ + 6y + 3y⁴)
= 4y⁴ - 8y³ - 5y³ - 6y - 3y⁴
= (4y⁴ - 3y⁴) + (- 8y³ - 5y³) - 6y
= y⁴ - 13y³ - 6y
Answer: y⁴ - 13y³ - 6y
