What you will do is 6.75 times 4 and the answer you should get is 27
8 - 7x^2 + 3 = 4x^2 - 1
8+3-7x^2 = 4x^2-1
11-7x^2 = 4x^2-1
B. Commutative property of addition
We can swap numbers and obtain the same results.
In this case, we swapped 8+3 and added them.
Answer:
The correct answer is 6.
Step-by-step explanation:
When translating and reflecting figures, the shape remains the same. So, the side of 2x-4 is corresponding to the side of 8 and they are equal to each other.
To solve, set up an equation like this to find x:
2x-4=8
Then, add 4 to both sides of the equation:
2x=12
The goal is to get x by itself and in order to do that, divide both sides by 2:
x=6
The value of x is 6. I hope this helps! ☺
