Answer:
17rx2−23rx−71x+75
Step-by-step explanation:
(17x−23)(xr−4)−(3x+17)
=(17x−23)(xr−4)+−1(3x+17)
=(17x−23)(xr−4)+−1(3x)+(−1)(17)
=(17x−23)(xr−4)+−3x+−17
=(17x)(xr)+(17x)(−4)+(−23)(xr)+(−23)(−4)+−3x+−17
=17rx2+−68x+−23rx+92+−3x+−17
=17rx2+−68x+−23rx+92+−3x+−17
=(17rx2)+(−23rx)+(−68x+−3x)+(92+−17)
=17rx2+−23rx+−71x+75
Use the way that kids use i.e trial and error method .
Solution:-
The set given by

Lets understand
- See the first term any natural value will make it natural .
Come to 2nd one.
- n should be a multiple of 8 to make it whole.
Come to third one
- n should be a number which makes the sum a perfect square by which we get a natural no.We have to solve it w.r.t to 2nd one
Lets think
Nearest squares to 225 are 196 and 289
We can't take 196 as we have to take a positive one other wise it will come in terms of i.
Take 289


Its divisible by 8 .
Rewrite the set



Hence n=64

Answer:
322 feet
Step-by-step explanation:
first lets plug in our value for s in the equation
.05(70)^2+ 1.1(70)
we then sqaure 70 to get
.05(4900) + 1.1(70)
Then multiply to get
245 + 77
then add to get
322 feet
