6x² - x - 15

Rewrite the expression by writing -x as a difference:

6x² + 9x - 10x - 15

Factor out 3x from the expression:

3x * (2x + 3) - 10x - 15

Factor out -5 from the expression:

3x * (2x + 3) - 5 * (2x + 3)

Factor out the expression:

(2x + 3) * (3x - 5)



Therefore the answer to your question would be:

D) 3x - 5

Dima020 [189]

Answer:

The value is T  =  \$54200

Step-by-step explanation:

From the question we are told that

      The  number of shares is  n  =  400

      The rate  of each share is  k  =  135\frac{1}{2}  =  135.5

Generally the total price is mathematically represented as

     T  =  400 * 135.5

      T  =  \$54200

A school has 360 students. 4/9 of them are girls. 3/5 of them are girls below the age of ten. How many girls are in the school a
quester [9]

To find total number of girls multiply total students by the fraction of girls:


360 x 4/9 = 360 x 4 = 1440/9 = 160 total girls.


If 3/5 are below the age of ten, that means 2/5 are above the age of ten.


Multiply the total number of girls by 2/5:


160 x 2/5 = 320/5 = 64


There are 64 girls above the age of ten.

If quadrilateral LMNO is a square, find the missing measures. Round your answers to the nearest tenth, if necessary. LN=46. What
aleksley [76]

The values of OM, PN, ON and MN of the given square are;

OM = 46

PN = 23

ON = 32.5

MN = 32.5

<h3>Pythagorean theorem</h3>

We are given;

LN = 46

  • Now, LN is the diagonal of the square and as such to get the sides of the square, we will make use of pythagoras theorem to get;

LO² + ON² = 46²

Since LO = ON, then;

2LO² = 46²

LO² = 46²/2

LO = √1058

LO = 32.5

Thus;

LO = ON = MN = 32.5

For the diagonals;

LN = OM = 46

Also; LP = PN = 46/2 = 23
