What is the factored form of this expression?

kirill [66]

Answer:

= (3t+2)(3t-2)(3t-4)

Step-by-step explanation:

Given the expression 27t^3 - 36t^2 - 12t + 16

On factoring:

(27t^3 - 36t^2) - (12t + 16)

= 9t²(3t-4)-4(3t-4)

= (9t²-4)(3t-4)

factoring 9t²-4

9t²-4 = (3t)² - 2²

From different of two square, a²-b² = (a+b)(a-b)

Hence (3t)² - 2² = (3t+2)(3t-2)

= (9t²-4)(3t-4)

= (3t+2)(3t-2)(3t-4)

Hence the factored form of the expression is (3t+2)(3t-2)(3t-4)

A New York taxi service charges a $3.25 boarding rate in addition to its meter which is $2 for every mile. How much does it cost

IgorC [24]

Answer:

Hey there!

This can be modelled by an equation, y=2x+3.25

For one mile: y=2(1)+3.25, or y=5.25

For twenty miles: y=2(20)+3.25, or y=43.25

Hope this helps :)
