4 x^2 - 32 = 8x
-8x -8x
4x^2 - 8x - 32 = 0
Factor the expression ...
4 ( x+2) ( x - 4) = 0
Set the factors equal to 0 ...
x + 2 = 0 x - 4 = 0
-2 -2 +4 +4
x = - 2 or x = 4
Answer:
10x + 6
Step-by-step explanation:
When distributing, you need to multiply the number on its own by both terms of the binomial (the 5x + 3). 5 times 2 is 10, and then you have the x, so it is 10x. Multiply 3 times 2 and get 6. Hope this helps!
Answers are......
<em><u>Explanation</u></em>
The given equation is:
First we will <u>simplify the left side by distributing 2</u>. So.......
Now <u>adding 8 to both sides and subtracting 5x from both sides</u>, we will get......
So, the solution is:
Charlie's solution is incorrect as he made a <u>mistake while distributing 2 on the right side</u>. The correct steps will be..........
The solution of Charlie's equation will be:
Answer:
The answer to your question is: 3) between 12 and 13
Step-by-step explanation:
Just get the square root of 151, and compare your result with the options.
√ 151 = 12.28
Then, the only possibility is (3) 12 and 13.
