The answer should be x=-4

Answer:

double, real root x = -4

Step-by-step explanation:

Please use " ^ " to indicate exponentation:  2х^2 + 8х = х^2 - 16.

Combine like terms:

х^2 + 8х = - 16.

Re-write in the standard form for a quadratic:

х^2 + 8х + 16 = 0

Recognize that this is the square of the binomial x + 4:

х^2 + 8х + 16 = 0  =>  (x + 4)^2 = 0

Solving this last result for x yields the double, real root x = -4.

Draw 8 lines that are between 1 inch and 3 inches long. Measure each line to the nearest fourth inch, and make a line plot.
IRISSAK [1]

The length of the line is the difference between the endpoints of the line

The length of each line to the nearest fourth inch is 0.25 inch

<h3>How to measure the length of each line</h3>

The length of the horizontal line is given as:

Length = 2 inches

This is calculated as:

Length = 3 inches - 1 inch

Length = 2 inches

8 lines are to be drawn between the 1 inch and 3 inches point.

So, the length (l) of each line is:

l = \frac{2\ inches}{8}

Simplify the fraction

l = \frac{1\ inches}{4}

Divide

l = 0.25\ inch

Hence, the length of each line to the nearest fourth inch is 0.25 inch

3(2x - 4) + x = 9<br> help with homework
natita [175]

6x - 12 + x = 9

6x + x - 12 = 9

Collect like terms

7x - 12 = 9

Add both sides 12

7x - 12 + 12 = 9 + 12

7x = 21

Divide both sides by 7

7x ÷ 7 = 21 ÷ 7

x = 3
