2x + 2x +2 are the integers
4x^2 + 4x^2 +8x +4 =884 (The sum of the integers squared)
8 x^2 +8x -880 = 0
x = 10
Therefore, the integers are:
20 and 22
Answer:
251.047804213 miles
Step-by-step explanation:
c1 t=3.5+1 speed 40 mph
c2 t=3.5 speed 50 mph
c1 40 *4.5= 180
c2 50 *3.5= 175
a^2+ b^2= c^2
180^2+175^2=c^2
32400+30625=c^2
63025=c^2
251.047804213=c
$34.60 rounds to $35
$24.99 rounds to $25
$527.85 rounds to $528
Now add the rounded numbers together:
$35
$25
$528
