Answer:
x = 5
Step-by-step explanation:
Simplify. First, combine like terms:
3x - x + 2 = 12
(3x - x) + 2 = 12
(2x) + 2 = 12
2x + 2 = 12
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
& is your order of operation.
First, subtract 2 from both sides:
2x + 2 (-2) = 12 (-2)
2x = 12 - 2
2x = 10
Next, divide 2 from both sides:
(2x)/2 = (10)/2
x = 10/2
x = 5
5 is your answer for x.
Check: Plug in 5 for x in the equation. Solve:
3(5) - (5) + 2 = 12
15 - 5 + 2 = 12
10 + 2 = 12
12 = 12 (True)

Answer:
A = 21572
Step-by-step explanation:
<em><u>The formula to find a rectangular prism's area is:</u></em>
A = 2wl + 2lh + 2hw
<em><u>OR</u></em>
A = 2(wl + lh + hw)
<em><u>So plug in the numbers into the formula accordingly:</u></em>
A = 2(47 · 66 + 66 · 68 + 68 · 47)
A = 2(3102 + 4488 + 3196)
A = 2(10786)
A = 21572
Answer:
<u>D. Lack of ability</u> because most of the portions came from someone else meaning he couldn't do it on his own.
Step-by-step explanation:
Not A because he was telling the truth in the report
Not B because he took responsibility of actually turning in the report
Not C because greed has to do with money and there was no money involved.
We know that
p(x) and f(x) ------------> both are defined by the equation of a straight line
g(x)----------> is a grade 2 or higher function
see the attached figure<span>Part A: What is the solution to the pair of equations represented by p(x) and f(x)?
the solution is the intersection both graphs
the solution is the point (-2,-3)
the answer part A) is the point </span>(-2,-3)
<span>Part B: Write any two solutions for f(x)
for x=-6 f(-6)=5
for x=-3 f(-3)=-1
</span><span>Part C: What is the solution to the equation p(x) = g(x)?
</span>the solution is the intersection both graphs
the solution is the point (0,2)
