Solve the inequality ?12<1/2(4x+16)<18
natita [175]

Answer:

<em>The solution will be:  2</em>

Step-by-step explanation:

The given inequality is:   12

First we will multiply all sides by 2 for eliminating that \frac{1}{2} in the middle part. So.........

2*12

Now, we need to subtract 16 from all sides. So, we will get........

24-16

Then, we will divide all sides by 4 for getting x alone in the middle part. So.......

\frac{8}{4}< \frac{4x}{4}< \frac{20}{4} \\ \\ 2

Thus, the solution will be:  2

PLEASE HELP!! Factor. 4x^2−49y^2
Zanzabum

Answer:

(2x-7y) (2x+7y)

Step-by-step explanation:

4x^2−49y^2

This is the difference of squares

a^2 - b^2 = (a-b) (a+b)

a^2 =4x^2   so a = 2x

b^2 = 49y^2  so b =7y

4x^2−49y^2 = (2x-7y) (2x+7y)
