Answer:
ghyohgfyu
Step-by-step explanation:
Y=(x+3)²+(x+4)²
y=x²+6x+9+x²+8x+16
y=2x²+14x+25
y=2(x²+7x+3.5²-3.5²)+25
y=2(x+3.5)²-2*3.5² +25
y=2(x+3.5)²+0.5
Answer:
(x²+1)(x-3)
Step-by-step explanation:
Factorize x³ + x - 3x² -3
x³-3x²+x-3
Factorize
x²(x-3)+1(x-3)
= (x²+1)(x-3)
Hence the factorized form is (x²+1)(x-3)
Answer:
71° F
Step-by-step explanation:
Consider the rational part of f(t)
( divide numerator and denominator by t³
= 
As t → infinity then 
→ 0 , the expression simplifies to
= 
= 40
Thus after driving for a long time
f(t) = 31 + 40 = 71° F
