Answer: 6,520 miles per year
Step-by-step explanation:
They had driven the car for 53,790 miles in 8.25 years.
The average number of number of miles driven per year is:
= 53,790 / 8.25 years
= 6,520 miles per year
<em>They drove an average of 6,520 miles per year.</em>
Answer:
A. t(x) = 450 - 0.06x
Step-by-step explanation:
The layer which is originally 450 m thick is decreasing by 0.06 m.
450 - 0.06
... per day. x represents days.
0.06x
So,
450 - 0.06x
Answer:
a² + 4 a + 4
Step-by-step explanation:
( a + 2 ) ( a + 2 )
Expand brackets
a² + 2 a + 2 a + 4
Simplify
a² + 4 a + 4
Answer:
√g *√g = g
Step-by-step explanation:
recall that any number or variable to the power of 1/2 can also be written as that variable or number under the radical.
So, we then have
√g * √g
Recall that when we multiply radicals, we multiply what is under our radicals together and then combine them under a new radical
√g * √g = √(g * g)
This gives us √(g²)
recall that the square root of a number or variable squared will merely result in the number or variable by itself (as these are reciprocate equations)
√(g²) = g
Answer:
25
Step-by-step explanation:
Note x^2y + xy^2 = xy(x+y)
We know xy = 5 and x+y = 5, so
5*5=25
