Answer:

x=3+√2 or x=3−√2

Step-by-step explanation:

For this equation: a=1, b=-6, c=7

1x2+−6x+7=0

Step 1: Use quadratic formula with a=1, b=-6, c=7.

−b±√b2−4ac

−(−6)±√(−6)2−4(1)(7)

2(1)

6±√8

x=3+√2 or x=3−√2

Answer:

x=37, Angle A is 74. Exterior angle B is 185

Step-by-step explanation:

I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree

angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

What is the solution to this inequality?

−4x−8>−20

Answers

Answer:

x < 3

Step-by-step explanation:

−4x − 8 > −20

Add 8 to both sides.

-4x > -12

Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

-4x/(-4) < -12/(-4)

x < 3

A male polar bear is 2 7/9 meters long. A female polar bear is 1 5/6 long. Sidney thinks the male polar bear is 1 2/3 meters longer than the female polar bear. She is incorrect. How did she get that answer?

Answers

Answer: See explanation

Step-by-step explanation:

The difference in the length of the polar bear will be:

= 2 7/9 - 1 5/6

The lowest common multiple of 9 and 6 is 18.

= 2 7/9 - 1 5/6

= 2 14/18 - 1 15/18

= 17/18

She is incorrect as she subtracted the denominator from the numerators and didn't find their lowest common multiple. She got the answer this way:

= 2 7/9 - 1 5/6

= (2 - 1) (7-5)/(9-6)

= 1 2/3
