The rate of trip 2 is 5 km/h
The time of trip 1 is 0.9-x hours
530.59
take the surface area of the cylinder (358.14)
and add it with the surface area of the cone(172.45)
Answer:
7x?
Step-by-step explanation:
The answer is the following: 16 multiplied by 2 equals= 32
And 81 multiplied by 3 equals 243
And since there are no lower forms the final answer will be 32/243
The pic is blurry, but looks like 18x²-21x-15
(3x-5)(6x+3) is the factored form.
3 and 6 are the factors of 18
-5, 3 or -3, 5 are the factors of -15
I line them up like this
3 -5
6 3
then I multiple them diagonally: 3*3=9, -5*6=-30, the sum of 9 and -30 is exactly -21, the coefficient for x. (If the sum doesn't make -21, I'd switch -5 and 3, or change to -3 and 5 to try again.)
so the factored form is (3x-5)(6x+3)
