Answer:

7x^2+4x-8=14

can be rewritten as

0=7x²+4x-22

everything divided by 7 to normalize

0=x²+4/7x+22/7

now throw the pq formula on this. We can treat it as a function.

the x-intercepts would be on

wait. there are indeed no real-number-solution to satisfy the given equation.

no x-intercepts, no solution. no numbers to put in for x so that the equation gives true results.

no solution in real numbers.

Have a nice day

If there are questions left, feel free to ask them

p.s. is this about imaginary numbers at university level?

Solve the equation square root X-6+2 = 6 for the variable. Show each step of your solution process

zhannawk [14.2K]

The first step would be to isolate the square root on the left side. √x-6+2 = 6 √x-6 = -2+6 √x-6 = 4We would have to take away the radical on the left and square the equation. (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22

Answer:

$\sqrt[4]{x^5}$

Step-by-step explanation:

A fraction exponent converts into a radical. The denominator is the index of the radical (farthest left number) and the numerator is the exponent of the base inside (the farthest right number). The base of the fraction exponent is the base number in green. To write this expression, simply the exponents into one exponent and one base.

$x^{\frac{3}{4}}x^{\frac{1}{2} } =x^{\frac{3}{4}}x^{\frac{2}{4} } =x^{\frac{3+2}{4}} =x^{\frac{5}{4}}$

Now convert to the radical.

$x^{\frac{5}{4}} = \sqrt[4]{x^5}$

Given ∠8≅∠12 .

Serggg [28]

Your answer would be B
When you have two angles, and want to know which lines must be congruent, you have to look at the transversal first. The two angles will share a side which is the transversal, and then their other side is one of the parallel lines.
The converse of the corresponding angles theorem states that If corresponding angles are congruent, then the lines are parallel.
