Answer:

x=61

Step-by-step explanation:

-3+\sqrt{2x-1} =8

\sqrt{2x-1} -3=8

<u><em>Add 3 to both sides of the equation:</em></u>

\sqrt{2x-1}-3+3=8+3

\sqrt{2x-1}=11

<u><em>Solve the square root:</em></u>

\sqrt{2x-1}=11

2x-1=11^{2}

2x-1=121

2x-1+1=121+1<em> {add 1 to both sides}</em>

2x=122

x=122/2

x=61

<u><em>hope this helps.......</em></u>

(2b) A rectangular prism measures 2 &amp; 2/5 inches by 3 &amp; 1/5 inches by 2 inches. How many cubes with edge length 1/5 inch
erastova [34]

Answer:

1920 cubes.

Step-by-step explanation

Turn both the mix numbers into improper fractions.

2 2/5 = 12/5

3 1/5 = 16/5

Then you will turn 1/5 into its reciprocal and multiply both the improper fractions by it. You can just casually multiply 2 and 5.

12/5 * 5/1 = 12

16/5 * 5/1 = 16

2 * 5 = 10

Next you multiply all together to get 1920 cubes.

(I could be missing a step. I apologize if I did.)

Use the quadratic formula to find the solutions to the
nadezda [96]

Answer:

D

Step-by-step explanation:

The quadratic formula:

\frac{-b\pm \sqrt{b^2-4ac}}{2a}

where a is the coefficient of x^2, b being the coefficient of x and c being the constant.

Plug in the values:

\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\cdot \:5}}{2\cdot \:2}

\frac{5\pm\sqrt{-15} }{4}

Since \sqrt{-15} =\sqrt{-1} \sqrt{15} =i \sqrt{15}

The answer is:

\frac{5\pm i \sqrt{15} }{4}
