Answer:

2x^3+17x^2+2x-3

Step-by-step explanation:

\left(2x+1\right)\left(x^2+8x-3\right)\\=2xx^2+2x\cdot \:8x+2x\left(-3\right)+1\cdot \:x^2+1\cdot \:8x+1\cdot \left(-3\right)\\=2x^3+17x^2+2x-3

In this equation, the variables were isolated to simplify the problem, following the order of operations. Negative-three either became an exponent or positive integer, 3, subtracted by a byproduct of the previous equation.

Solve the inequality for x. -4x -6 <50
Nostrana [21]

Answer:

x >-14

Step-by-step explanation:

To solve the inequality, we need to isolate the variable, x

-4x -6 <50

Add 6 to both sides

-4x <56

Divide both sides by -4

Since we divided by a negative number, we must flip the inequality sign

x <-14

Flip the inequality sign

x> -14
