Pls explain<br><br> 5/6 - 8/7 - 7/10

Nadusha1986 [10]

Answer:

Step-by-step explanation:

5/6 - 8/7 - 7/10

The first step to adding or subtracting fractions is to find a common denominator among all the fractions. In this case, the largest number that has a mutiple of 6, 7 and 10 is 210.

\frac{5}{6}-\frac{8}{7}=\frac{7}{10}

$\frac{175}{210}-\frac{240}{210}-\frac{147}{210}$

$\frac{-212}{210}$

-106/105

Solve the following equations by using the Quadratic formula and answer the subsequent questions:

OleMash [197]

Answer:

Step-by-step explanation:

Note that x^2 - 6x + 9 = 0 can be rewritten as the square of a binomial:

(x - 3)^2

and the roots are found by setting this equal to zero and solving for x:

(x - 3)^2 = 0, or x - 3 = ±0, or x = 3 and x = 3

a) there are two equal roots: {3, 3}

b) the roots {3, 3} are rational

c) the roots {3, 3) are real

If you want to use the quadratic formula, proceed as follows:

1. Identify the coefficients of the quadratic: {1, -6, 9}

2. Find the discriminant b^2 - 4ac: It is (-6)^2 - 4(1)(9) = 36 = 36 = 0

As a general rule, if the discriminant is zero, the quadratic has two equal, real roots. These roots are rational: 3 can be rewritten as 3/1, which is a ratio.
