Answer: x² - x - 12
Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.
<em>First, Outer, Inner, Last</em>.
We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.
So we have x² - 4x + 3x - 12.
Simplifying from here by combing the middle terms, we have x² - x - 12.
Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.

Step-by-step explanation:
Graphing an inequality is when you shade in the graph based on whether your point that you chose(usually (0, 0)) is true or false when put back in the original equation.
Graphing an equation of a line is just a line on the graph.
For a solid line: the inequality should be greater then or equal to or less then or equal to.
For a dashed line: the inequality should just be greater then or less than.
Hope this helps for your inequality equations :)

<u>Evaluating Algebraic Expressions</u>
Given an expression where variables (letters) are included, evaluate the expression at specific values of the variables means to substitute the values into the expression, operate, and give the final result.
The expression provided in the question is:
4m + 3
Evaluate at m=5
Substitute m for 5 recalling 4m really means 4*m, a product:
4*5 + 3 = 20 + 3 =23
Answer:
58
Step-by-step explanation:
45=((3x+11)+(10x-12))÷2
90=13x-1
13x=91
x=7
ML=10(7)-12
=58
