Y= 6(x - 4)(x - 4) - 1
y= 6x^2 - 48x + 95
you just have to foil it.
hope i help
Answer:
Step-by-step explanation:
Given
sunny day speed= s mph
Rainy day speed=s+1 mph
Derek average speed =2.8 miles/hr
s<2.8<s+1
so on sunny day speed must be 2 mph
and on rainy day speed must be 3 mph

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

Let 


Fraction of distance traveled on sunny weather

X+y = 4, -----> y=4 - x
x² +(4-x)² =16
x² +16-2*4x+x² =16
2x² - 8x = 0
x(2x-8) = 0
2x-4=0, 2x=8, x=4
x=0 or x=4
If x=0, y=4-x=4-0=4.
If x=4, y= 4-x=4-4=0.
(0,4) or (4,0)
Check
x² +y² =16
For (0,4)
0²+4² =16
16 =16 True
For (4,0)
4² +0²=16
16=16 True
Answer (0, 4) and (4,0).
Answer:
Distance between the points (-3,1) and (1, -2),



Option C
18/20 = 9/10
