Mathematics

liq [111]3 years ago
8 0

Answer:

5(x+6)

Step-by-step explanation:

hope this is helpful

factorise an expression, we need to take out any factors that are common to each term. The process is the opposite of expanding brackets. To make sure an expression is fully factorised, we need to identify its highest common factor (HCF), ie the biggest number/letter that each term can be divided by.

The fair will be traveling to a place that uses the metric system. They received directions to their next stop, but they are in
MariettaO [177]

Answer:

2x - 0.4x ;

8x/5 ;

Yes

Step-by-step explanation:

Let number of miles = x

Arlene:

Double number of miles = 2 * x = 2x

Subtract 20% of the result :

2x - 20% of 2x ;

2x - 0.4x

Raul:

Divides Number of miles by 5 ; x / 5

Multiplies result by 8 ;

8 * (x/5) = 8x /5

To know if expressions are equivalent :

Let x = 10 miles

Using Arlene's expression:

2x - 0.4x

x = 10

2(10) - 0.4(10) = 16

Using Raul's expression :

8x / 5

(8*10) / 5

80/5

= 16

Since they give the same result, we can conclude that the expression are equivalent

The closer the slope value is to zero, the steeper the line. yes or no
Harrizon [31]
No, that is not true. Use the website desmos.com to try it out yourself. Graph equations like y=1x, y=1/2x, and y=1/4x to try. Then, you will see that as the number gets bigger, the line gets steeper (it gets higher..like a hill..rising..)
