Answer:
Three times a number plus 16
To solve this, we simply need to break down the words and turn each part into an equation.
"Three times"
This shows that we will be multiplying 3 and something.
3*
"a number"
This shows that the number we will be multiplying 3 by is "n," which represents a number.
3*n or 3n
"plus 16"
This shows we will be adding 16 to the rest of the equation.
3n+16
Using the logic above, we can see that the equation to represent this is 3n+16.

Step-by-step explanation:
Answer:
-x+4
Step-by-step explanation:
given that
(x^3-4x^2+7x-28)÷(x^2+7)
or
first (x^2+7) × -x = -x^3-7x
so (x^3-4x^2+7x-28) + (-x^3-7x) = -4x^2-28
agian (x^2+7)×(4) = 4x^2+28
so, (-4x^2-28) + (4x^2+28) = 0
X+17+76=180
subtract 17 and 76 on both sides
x=87
