2/8 *1/7

Multiply the numerators together.

(2)(1)=2

Multiply the denominators together.

(8)(7)=56

2/56 - reduce

divide by 2 for the numerator and denominator

2/2=1

56/2=28

2/8 *1/7= 1/28 ( Answer)

Answer:

<u>1/28</u>

Step-by-step explanation:

Alrighty, so you start off with 2/8 x 1/7, you just have to multiply across (2x1 (numerator) and 8x7 (denominator) and you will get 2/56.

Now, you have to simplify this fraction. The number 2 goes into both the numerator and denominator, so, divide 2 by 2 (1) and 56 divided by 2 (28).

Your answer should be 1/28.

Hope this helps! ^-^

The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q
Irina-Kira [14]

9514 1404 393

Answer:

  q = 40

Step-by-step explanation:

When the quadratic has roots p and r, it can be factored as ...

  (x -p)(x -r) = x² -(p+r)x +pr

So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...

  p + r = 14

  p - r = 6

  2p = 20 . . . add the two equations

  p = 10

  r = 14 -p = 4

The value of interest is then ...

  q = pr = (10)(4)

  q = 40

__

The graph shows the roots to be 4 and 10, as we found.

Two sides of a triangle measure 8 cm and 15 cm. Whi[:h could be the length of the third side?
lutik1710 [3]

18 cm is correct .

Step-by-step explanation:

The sum of two smaller sides is greater that the largest side.

It is given that the two sides of a triangle measure 8 cm and 15 cm.

Case 1: Let 8 cm and 15 cm. are smaller side. So,

<em>Third side < 8 + 15</em>

<em>Third side < 23</em>

<em>It means 3rd side must be less than 23</em>

<em>Case 2: Let 15 cm is the largest side.</em>

<em>15 < Third side + 8</em>

15 - 8 < Third side

7 < Third side

It means 3rd side must be greater than 7.

Since only 18 is less than 23 and greater than 7, therefore the possible length of third sides is 18 cm and option 2 is correct.

Solve each equation <br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3x-2%7D%7Bx%2B%204%7D%20%3D0%5C%5C%5C%5C%5C%5C%5Cfrac%7B2%7
Sloan [31]

The expression (3x - 2)/(x + 4) = 0 has a value of x is 3/2. Amd the expression 2/(x + 4) = 0 has a value of x is ∞.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

The expression is given below.

(3x - 2)/(x + 4) = 0

Then on simplifying, we have

3x - 2 = 0

    3x = 2

      x = 3/2

And

2/(x - 3) = 0

         2 ≠ 0

More about the simplification link is given below.
