Answer:

= 2x²( 2x+ 1) + 2x

= 2x (2x² + x + 1)

Step-by-step explanation:

Given in the question two functions,

f ( x ) = 9x³ + 2x² − 5x + 4

g ( x ) = 5x³ − 7 x + 4

To find,

f ( x ) − g ( x )

Substitute each functions

= 9x³ + 2x² − 5x + 4 - ( 5x³ − 7 x + 4 )

Remove parentheses

= 9x³ + 2x² − 5x + 4 - 5x³ + 7 x - 4

Combine like terms and add them up

= 4x³ + 2x² + 2x

Factorise

= 2x²( 2x+ 1) + 2x

= 2x (2x² + x + 1)

So the final answer in factored form is 2x²( 2x+ 1) + 2x or 2x (2x² + x + 1)

This can't be further factorise because answer will be in complex numbers

Answer:

500 minutes

Step-by-step explanation:

Assume you need solution as you have the answer

The full time is x
24% of x is 120 minutes

Find x:

x*24/100 = 120
x *0.24 = 120
x = 120/0.24
x = 500

Answer: See the attached image

You have the correct idea for the boxes you've filled out. For the first three boxes in column 1, I would be specific which segments you are dividing. So for instance, in the first box, it would be EG/EB = 55/11 = 5. Then the second box would be EF/EC = 35/7 = 5, and so on. The order of the boxes doesn't matter. The three boxes then combine together to help show that the triangles are similar. Specifically $\triangle EFG \sim \triangle ECB$ . The order of the letters is important to help show how the angles pair up and how the sides pair up. We use the SSS similarity theorem here.
