Solve for “x” 4x + 7 = 5

rewona [7]

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>

$GCF = 5(x+7)^2$

Solution:

Given that,

We have to find the greatest common factor

$5(x+7)^4\\\\35(x+7)^2\\\\15(x+7)^3$

First find the GCF of numbers 5, 35 and 15

Find the GCF of 5, 35 and 15

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

$(x+7)^4\\\\(x+7)^2\\\\(x+7)^3$

Here, the common factor is $(x+7)^2$

Thus, GCF for given expression is:

$GCF = 5(x+7)^2$
