Factoring 3xsquared + 14x +20

1 answer:

6 0

The equation (3xsquared+ 14x + 20 = 0) has no real roots, so there are no factors made of only real numbers.

The factors are [ -7 plus and minus ( i x square root of 11 ) ]

" i " is the square root of -1 .

Answer:

k = 45*

2k = 90*

K will be the same as the 45* degrees, as it is across from it.

Answer:

x = $3\sqrt{13}$ = 10.8

Step-by-step explanation:

Both problems are done the same way. I will do the first one and you do the second one. OK?

Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,

$6^{2} + 9^{2} = x^{2}$

$x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}$ = 10.8

None of the answer choices are to the nearest tenth. So, I am confused about that.

In the second problem, the answer should be 11.2
