Select all the statements that are true for any value of x.
A. 7x + (2x + 7) = 9x + 7
B. 7x + (2x - 1) = 9x + 1
C. 3x + (10 - 3x) = 10
D. 5x – (8 - 6x) = -x - 8
E. 4x - (2x + 8) = 2x - 8
F. 6x - (2x - 4) = 4x + 4
Answer:
A,C,E,F
Step-by-step explanation:
when it is 0=0 it means it is true for all. or x=x.
The true statements for x are letters: A,C, E, and F.
Addition Sign RulesHere it is important to remember the rules for the addition of integers numbers:
+ + Add Final result (+) - Final result (+)
- - Add Final result (-) - Final result (-)
+ - Subtract - Final result (the sign of the integer having a greater value)
- + Subtract - Final result (the sign of the integer having a greater value)
Multiplication Sign RulesThe rules for multiplication of numbers are:
+ + or - -
The result presents a positive sign (+) because the signs are the same.
+ - or - +
The result presents a negative sign (-) because the signs are different.
For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

10x- (- 4 + 7x
answer if you can :)
Answer:
17x + 4
Step-by-step explanation:
The -(- would be turned into a positive due to the rule of two negatives makes a positive. You wouldn't add the 4 into either of the numbers with a variable, you would only add the 10x and 7x.
Answer:
3x+4
Step-by-step explanation:
Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.

What is the area, in square units, of the parallelogram shown below?
A parallelogram ABCD is shown with height 12 units and base 8 units.
(1 point)
12 square units
24 square units
48 square units
96 square units
To figure out the area of a parallelogram, we need to identify its formula. However, I do know the formula, which is Area = Base x Height.
Area = Base x Height
Area = 8 x 12
= 96 cm squared
Therefore, the answer it 96 cm squared. By the way, I recommend that you review and comprehend the topic regarding area. Try memorizing all formulas for the shapes.
Rectangle & Square: Area = length x width
Triangle: Area = base x height
2
Trapezoid: Area = (Base 1 + Base 2) x h
2
Pararellogram: Area = base x height
Circle: Area = pi x r sqaured
Those are all the formulas I can recall; however, there might be more.

X=
PLEASE HELP!!! Fast!!!
Answer:
x=2
Step-by-step explanation
The First step is to distribute the '2" into the parenthesis.
thus, you have 8x + 8 = 24
now we need to get x by itself so we will subtract 8 from both sides to get 8x by itself.
we know have 8x = 16
now divide by 8 to get x
x=2

What is the slope of the line shown?
Please note that anyone who answers this post with random letters and or numbers that have nothing to do with this mathematics problem will be deleted or reported.
Hello!
[tex]\large\boxed{Slope = -\frac{1}{2}}[/tex]
Use the slope formula along with provided points to solve for the slope.
We can use the points (-4, -1) and (0, -3) and plug these values into the equation:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m = \frac{-3-(-1)}{0-(-4)} \\\\m = \frac{-2}{4} \\\\m = -\frac{1}{2}[/tex]

Answer:
Just read explanation
Step-by-step explanation:
In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal. It can also be defined as a parallelogram containing a right angle. A rectangle with four sides of equal length is a square. The term oblong is occasionally used to refer to a non-square rectangle. A rectangle with vertices ABCD would be denoted as ABCD.
