You can set proportions up 4 ways.
See picture. Sorry you got the wrong answer.
Answer:
x=-1/2 or -0.5
Step-by-step explanation:
You would subtract 7 on both sides and that leaves you with 4x=-2 then you would divided by 4 to get x=-0.5
Answer:
Step-by-step explanation:
The answer is 4.
Once you add 4, you get:
x^2 -2x + 4 = 7.
The left side is factorable:
(x-2)^2 = 7.
There is your perfect square.
<h3>GCF for given expression is:</h3>

<em><u>Solution:</u></em>
Given that,
We have to find the greatest common factor

First find the GCF of numbers 5, 35 and 15
<em><u>Find the GCF of 5, 35 and 15</u></em>
The factors of 5 are: 1, 5
The factors of 15 are: 1, 3, 5, 15
The factors of 35 are: 1, 5, 7, 35
Then the greatest common factor is 5
Now find the GCF of variables

Here, the common factor is 
<em><u>Thus, GCF for given expression is:</u></em>

The points do have a linear pattern, and the correlation will be positive.
