Who can finish this for me
Paladinen [302]

Answer:

<h2>-  {x}^{4}  - 7 {x}^{3}  + 8</h2>

Step-by-step explanation:

(5 - 5 {x}^{4}  -  {x}^{3} ) - (6 {x}^{3}  - 4 {x}^{4}  - 3)

Remove unnecessary parentheses

5 - 5 {x}^{4}  -  {x}^{3}  - (6 {x}^{3}  - 4 {x}^{4}  - 3)

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

5 - 5 {x}^{4}  -  {x}^{3}  - 6 {x}^{3}  + 4 {x}^{4}  + 3

Collect like terms

5 + 3 - 5 {x}^{4}  + 4 {x}^{4}  -  {x}^{3}  - 6 {x}^{3}

5 + 3 -  {x}^{4}  - 7 {x}^{3}

Add the numbers

8 -  {x}^{4}  - 7 {x}^{3}

Use the commutative property to reorder the terms

-  {x}^{4}  - 7 {x}^{3}  + 8

Hope this helps...

Best regards!!

The function D(t)=18t2−130t gives the distance a car going a certain speed will skid in t seconds. Find the time it would take f
Assoli18 [71]

The time it will take for the car to skid for 150 feet is 8.23 seconds.

<h3>How to find the time the car will skid?</h3>

The function D(t) = 18t² − 130t gives the distance a car going a certain speed will skid in t seconds.

The time the it would take for the car to skid for 150 feet can be calculated as follows:

Therefore,

D(t) = 18t² - 130t

150 =  18t² - 130t

18t² - 130t - 150 = 0

divide by 3

9t² - 65t - 75 = 0

Hence,

t = 65 ± 5√277 / 18

t = 8.23425471586 or -1.01166666667

Hence,

t = 8.23 seconds.

Therefore, the time it will take for the car to skid for 150 feet is 8.23 seconds.
