Answer:

The answer to your question is letter C.117

Step-by-step explanation:

The original expression is: uv² +5uv + u²

and u= 3 and v = 4

Then: (3)(4)² + 5(3)(4) + (3)²        Substitution

          (3)(16) + 5(12) + 9             Expanding

          48 + 50 + 9                      Simplify

          117                                    Result

The answer is X = 6

Because 3 times 2 x is 6x ... then -1 plus 1 is 0 so it levels out and x is 6

Solve 6x - 3y = 12 for y<br> A. y = 6x + 4<br> B. y = 2x - 4<br> C. y = -6x + 12<br> D. y = 2x - 12
DedPeter [7]

Answer: <em>y = 2x − 4</em>

The correct answer is <em>B)</em> <em>y = 2x − 4</em>

Step-by-step explanation:

<u>Move all terms that don't contain y to the right side and solve:</u>

<em>y = −4 + 2x</em>

<u>Then reorder −4 and 2x:</u>

<em>y = 2x − 4</em>

<u>Final answer is:</u>

<em>B) y = 2x − 4</em>
