Answer:
4262
Step-by-step explanation:
2 + 7x^2- 2x^3-8x +7x^4 at x = 5
= 2 + 7*(5)^2 - 2*(5)^3-8*5 +7*(5)^4
=2+175-250-40+4375
=4552-290
=4262

Always- their slopes are always opposite reciprocals of each other
This photo will show you how to do it and the answer so your welcome
Length is l
width is w
l*w = 30
2l + 2w = 34
You can simplify the second equation to l + w = 17
Factors of 30:
30*1
15*2
10*3
6*5
Try adding each of these factors together, to find out which equals 17
30 + 1 = 31
15 + 2 = 17
10 + 3 = 13
6 + 5 = 11
So the dimensions of the rectangle are 15m * 2m
