Answer:
6x - 9y = -12
Step-by-step explanation:
2x - 3y = -4 multiply both sides by 3 by adding paranthesis to represent this
3( 2x - 3y ) = 3 (-4) Then use distributive property for the left side equation
6x - 9y = -12 Finally just multiply -4 by 3 and you get this equation
To evaluate this expression, we simply plug the value of the variable into the expression and solve.
Since m = -4, plug a -4 in for m every time the m appears in the expression.
So we have (-4)^2 + 6(-4) + 3.
Start by simplifying the exponent.
(-4)^2 is 16.
Now multiply.
A positive times a negative is a negative.
So 6(-4) is -24.
So we have 16 + 24 + 3 which is 43.

Answer:
<h2><em>
14 x + 11</em></h2>
Step-by-step explanation:
4*(2x - 1) + 3*(2x + 5) =
8x - 4 + 6x + 15 =
14 x + 11
You're equation will look like:
R = 1167 + 1167 + 1167 - 239
To get the answer, simplify
R = 1167 + 1167 + 1167 - 239 = 3262
