You can simplify the entire equation by dividing it all by 7, resulting in 7(b^2-6b+20). 

Here, you can factor as you normally would. Your X values would have to be found using the quadratic formula.

Which two square roots are used to estimate√8?
riadik2000 [5.3K]

Answer:

Option C.

Option B.

Step-by-step explanation:

By definition, the square of a number is that number times itself.

The square root of a perfect square is a whole number.

Since the square root of another number (not perfect square) is not a whole number, you can estimate it finding two perfect square roots that number is between.

1) Observe that 4 and 9 are perfect squares:

4=2^2\\9=3^2

And 8 is between those numbers.

Therefore, the square roots \sqrt{4} and \sqrt{9} are used to estimage \sqrt{8}

2) Notice 36 and 49 are perfect squares:

36=6^2\\49=7^2

And 42 is between those numbers.

Therefore, the square roots \sqrt{36} and \sqrt{49} are used to estimage \sqrt{42}

Look at picture and solve​
Aleks04 [339]

Step-by-step explanation:

As we can see, the line on the bottom is a perfectly straight 180º line, so the two angles, a and 50º are supplementary angles. Remember: Supplementary angles = 180º, and complementary angles = 90º.

Since this is a 180º line, all we have to do is to subtract 50 from 180 to get our angle a.

180-50 = 130º

Our answer: a = 130º
