Find the value of expression - 17x-19xpwer4 - 21x power 2,when x=3<br><br>​
Marrrta [24]

Answer:

-17x - 19x^4 - 21x^2 = -1779 when x = 3

Step-by-step explanation:

Given

-17x - 19x^4 - 21x^2

x = 3

Required

Solve

Substitute 3 for x in -17x - 19x^4 - 21x^2

-17x - 19x^4 - 21x^2 = -17*3 - 19*3^4 - 21*3^2

Evaluate all exponents

-17x - 19x^4 - 21x^2 = -17*3 - 19*81 - 21*9

-17x - 19x^4 - 21x^2 = -51 - 1539- 189

-17x - 19x^4 - 21x^2 = -1779

I need help with this question please
nasty-shy [4]

Answer:

YES

Step-by-step explanation:

First, let's find the total number of seats int he airplane.

14 + 64 + 4 * 108 = 510

The airplane has a total or 510 seats.

Half of the number of seats is 510/2 = 255.

Now let's calculate the number of seats being used and compare with 255.

5/7 * 14 + 5/16 * 64 + 5/9 * 4 * 108 =

= 2 * 5 + 4 * 5 + 12 * 4 * 5

= 10 + 20 + 240

= 270

270 seats are being used.

270 is greater than 255, so more than half of the seats are being used.

Answer: YES
