Answer:

b. {x}^{2}  - 7x - 18

Step-by-step explanation:

Area of shaded region

= (2x + 4)(x - 5) - (x + 2)(x - 1) \\  \\  = 2 {x}^{2}  - 10x + 4x - 20 \\  -  {x}^{2}  +  + x - 2x + 2 \\  \\  =  {x}^{2}  - 7x - 18

What is the product of (3x-9) and 6x↑2-2x+5 Write your answer in standard form.
klio [65]

Answer:

a. 18x^3 -60x^2 + 33x - 45

b. No

Step-by-step explanation:

Given:

(3x-9) and 6x^2-2x+5

=> the production of them is:

(3x-9)(6x^2-2x+5) , we will use distributive law to solve this To do that. we first multiply  6x^2-2x+5 by 3x then by -9. This is done as follows

= 3x (6x^2-2x+5) - 9(6x^2-2x+5)  = (3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)\\\\= (18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)

Then Open both brackets

= 18x^3 -6x^2+ 15x -54x^2 + 18x -45

After that, we group the same terms

= 18x^3 -(6x^2 +54x^2)+ (15x  + 18x) -45

= 18x^3 -60x^2 + 33x - 45

(b) Is the product of (3x-9) and  6x^2-2x+5  equal to the product of (9x-3) and 6x^2-2x+5

No, let find the product of (9x-3) and 6x^2-2x+5 , we will use distributive law to solve this as the above example.

= (9x-3)(6x^2-2x+5)

= 9x (6x^2-2x+5) - 3(6x^2-2x+5)

=(9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)

= (54x^3  - 18x^2+ 45x) - (18x^2 - 6x +15)

After that, we open the bracket to find the same terms

= 54x^3  - 18x^2+ 45x -18x^2 + 6x -15

= 54x^3  - 18x^2 -18x^2 + 45x  + 6x -15

= 54x^3  - 36x^2 + 51x  -15  

As you can see 54x^3  - 36x^2 + 51x  -15   ≠18x^3 -60x^2 + 33x - 45

Hope it will find you well.

in a canoe race, a team paddles downstream 480 m in 60 s. The same team makes the trip upstream in 80 s. Find the team's rate in
Vera_Pavlovna [14]
480=60(v+s) 

480=60v+60s

8=v+s

s=8-v...

480=80(v-s)  using s from above we get:

480=80(v-(8-v))

6=v-8+v

6=2v-8

2v=14

v=7, and since s=8-v, s=1

So the rate of the team is 7m/s while the rate of the stream is 1m/s
