Answer:
b.d-6 that's the correct answer
Answer:
total distance= 12000+12000=24000
total time = 5+6=11
average speed of plane= 24000/11
Let x is the smaller integer.
x+12 is the larger integer because two integers differ by 12.
The sum of their square means
x² + (x+12)² = 74
x² + x² + 24x + 144 = 74
2x² + 24x + 70 = 0
2(x² + 12x + 35) = 0
2(x+5)(x+7) = 0
x = -5 or - 7
so we have two answer.
first x = -5 as smaller and 7 as the larger x = -5 + 12 = 7
second x = -7 as smaller and 5 as the larger. x = -7 + 12 = 5
Answer:
Yes, they are equivalent.
Step-by-step explanation:
-5 + -2 = -7
-5 -2 = -7
x=smaller numb
7/30 = 2/x
7x=60
x=8.57
