Ab+ac=a(b+c) where a is the greatest common factor
find greatest common factor of 10 and 50
10=1,2,5,10
50=1,2,5,10,25,50
greatest common is 10
a=10
10(1)+10(5)=10(1+5)=10(6)=60

Juanita begins to factor an expression as shown. x2+3x−18=(x+)(x−) What numbers should be placed in the boxes from left to right

stich3 [128]

Answer:

Option A is the correct answer.

Step-by-step explanation:

Here we need to factorize x²+3x−18

The coefficient of x is 3 and the constant is -18

Which means

The sum of factors is 3

The product of factors is -18

The factors satisfying are 6 and -3

Here the factors are given in the type (x+)(x−)

So the value after plus is 6 and value after - is 3

Option A is the correct answer.

A business is owned by 3 people. Mrs. Applegate owns

Bezzdna [24]

Given:

Mrs. Applegate owns $\dfrac{3}{19}$ of the business.

Mrs. Brown owns 3 times as much as Mrs. Charles.

To find:

The fractional part of the business that Mrs. Brown owns.

Solution:

Let Mrs. Charles owns x part of business.

Mrs. Brown owns 3 times as much as Mrs. Charles.

Mrs. Brown owns = 3x part of business.

Mrs. Applegate owns $=\dfrac{3}{19}$ of the business.

$x+3x+\dfrac{3}{19}=1$

$4x=1-\dfrac{3}{19}$

$4x=\dfrac{19-3}{19}$

$4x=\dfrac{16}{19}$

Divide both sides by 4.

$x=\dfrac{16}{4\times 19}$

$x=\dfrac{4}{19}$

Now,

Mrs. Brown owns $=3\times x$

$=3\times \dfrac{4}{19}$

$=\dfrac{12}{19}$

Therefore, Mrs. Brown owns $\dfrac{12}{19}$ of the business.
