Answer:
they will tie
Step-by-step explanation:
if you divied 7 in to 70 you get 7 and if you divied 5 into 35 it 7
It takes both of them 7 mins to complet a mile
Answer:
see below
Step-by-step explanation:
9(7 + 2x)
The two factors are 9 and 7+2x
9 has one term and 7 +2x has two terms
The coefficient of the variable term is 2. x is the variable
It depends on what x is. For example, if x=4 then the difference between 15 and x would be 11.
Hope this helps!
The formula for the circumference of a circle is π x diameter
Since we already know the circumference, we divide that by π to get the diameter:
circumference = π x diameter
so
circumference / π = diameter
Now lets do this:
31.4 / π = 9.9949... (this is the diameter)
-----------------------------------------------------------------------
The formula for the area of a circle is π r²
To get the radius, we just halve the diameter:
9.9949.. / 2 = 4.99746...
Now that we know the radius we can use the formula:
π x r²
= π x 4.99746²
= 78.46ft²
So the area is:
78.46ft²
27x^2 - 42x + 12
If x = 2:
27(2)^2 - 42(2) + 12
= 27(4) - 84 + 12
= 108 - 72
= 36
