Answer:

Hence the expression $$(3r-8)(11r+1)=33r^2-85r-8$$.

Step-by-step explanation:

Explanation

  • The given expression is (3 r-8)(11 r+1).
  • We have to multiply the given expression.
  • Multiply the (3 r-8) by 1 , multiply the (3 r-8) by 11r then add like terms.

$$\frac{\begin{matrix}{} & {} & 3r & - & 8 \\ \times & {} & 11r & + & 1 \\ \end{matrix}}

___________

{\frac{\begin{matrix}{} & {} & 3r & - & 8 \\ 33{{r}^2} & - & 88r & {} & {} \\ \end{matrix}}{\begin{matrix}33{{r}^2} & - & 85r & - & 8 \\ \end{matrix}}}$$

How many solution does 6-3x=4-x-3-2x
-Dominant- [34]

Answer:

Step-by-step Simplifying

6 + -3x = 4 + -1x + -3 + -2x

Reorder the terms:

6 + -3x = 4 + -3 + -1x + -2x

Combine like terms: 4 + -3 = 1

6 + -3x = 1 + -1x + -2x

Combine like terms: -1x + -2x = -3x

6 + -3x = 1 + -3x

Add '3x' to each side of the equation.

6 + -3x + 3x = 1 + -3x + 3x

Combine like terms: -3x + 3x = 0

6 + 0 = 1 + -3x + 3x

6 = 1 + -3x + 3x

Combine like terms: -3x + 3x = 0

6 = 1 + 0

6 = 1

Solving

6 = 1

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.
