If you are adding two fractions that are both greater than 1/2, what must be true about the sum? Give three examples to support

slavikrds [6]

Answer:

The sum must be greater than 1

Step-by-step explanation:

Two fractions that are greater than 1/2 let's say

<u>Example 1</u>

3/4 and 7/8, the sum will be

3/4+7/8 with LCM of denominator as 8 sum= $\frac {(3*2)+7}{8}=\frac {13}{8}=1\frac {5}{8}$ which is more than 1

<u>Example 2</u>

6/9 and 5/8 with the LCM of denominator as 72, the sum= $\frac {(6*8)+(5*9)}{72}=\frac {93}{72}=1\frac {7}{24}$ which is greater than 1

<u>Example 3</u>

8/9 and 7/9 with the LCM of denominator as 9, the sum= $\frac {8+7}{9}=\frac {15}{9}=1\frac {2}{3}$ which is greater than 1

-6(p+8)=36<br><br> Algebra two step equation

Tatiana [17]

Answer:

The value of p = -14

Step-by-step explanation:

Given the equation

$-6\left(p+8\right)=36$

Divide both sides by -6

$\frac{-6\left(p+8\right)}{-6}=\frac{36}{-6}$

simplify

$p+8=-6$

Subtract 8 from both sides

$p+8-8=-6-8$

simplify

$p=-14$

Therefore,

The value of p = -14

You are told that a third powered polynomial has zeroes at -1, 2, 5.

vichka [17]

Answer:

a) factors of polynomial are: (x+1)(x-2)(x-5)

b) the required polynomial in standard form is: $\mathbf{x^3-6x^2+3x+10}$

Step-by-step explanation:

The polynomial has zeros at -1,2,5

Part A) Write the three factors of the polynomial

we have x=-1, x=2 and x=5 as zeros of polynomial

so factors will be:

(x+1)=0, (x-2)=0, (x-5)=0

So, factors of polynomial are: (x+1)(x-2)(x-5)

Part B) Write the polynomial in standard form

For finding polynomial, we will multiply all the factors i.e

(x+1)(x-2)(x-5)

$(x+1)(x-2)(x-5)\\=(x(x-2)+1(x-2))(x-5)\\=(x^2-2x+x-2)(x-5)\\=(x^2-x-2)(x-5)\\=x(x^2-x-2)-5(x^2-x-2)\\=x^3-x^2-2x-5x^2+5x+10\\=x^3-x^2-5x^2+5x-2x+10\\=x^3-6x^2+3x+10$

So, the required polynomial in standard form is: $x^3-6x^2+3x+10$
