Of the following, which is the solution to 2x2 − 5x = −8? the quantity negative five plus or minus i times the square root of thirty nine over four the quantity five plus or minus i times the square root of thirty nine over four the quantity five plus or minus i times the square root of thirty nine over two the quantity negative five plus or minus i times the square root of one hundred ninety two over two

Answer:

Step-by-step explanation:

find the solution to

To solve the equation for x , we need to make right hand side 0

, add 8 on both sides

Now use quadratic formula to solve for x

the value of a=2, b=-5 and c=8

Plug in all the values and solve for x

We cannot simplify more

2x²-5x+8=0

use the quadratic formula, x=(5+√39i)/4 of x=(5-√39i)/4

looks like the second choice is correct.

use the quadratic formula, x=(5+√39i)/4 of x=(5-√39i)/4

looks like the second choice is correct.

Can a triangle be drawn with the following angle measures? Why or why not? 45°, 55°, 65°

Every/Any triangle needs to sum up to 180 degrees. To figure out if our angles make a triangle, let's sum them up.

45 + 55 = 100.

100 + 65 = 165.

This does not equal 180, so no, it does not make a triangle.

45 + 55 = 100.

100 + 65 = 165.

This does not equal 180, so no, it does not make a triangle.

The sum of the measures of the interior angles of a triangle is 180 degrees.

45 + 55 + 65 = 165

This does not equal 180 so the answer is no.

45 + 55 + 65 = 165

This does not equal 180 so the answer is no.
