Combine and simplify these radicals

Step-by-step explanation:

A

Step-by-step explanation:

One property of radicals is that if we have the nth root of a multiplied by the nth root of b:

Here, we have the square root of 8 multiplied by the square root of 20, so we can combine these into one radical:

160 can be written as: 4² * 10. So, we have:

We know that the square root of 4 squared is simply 4, but we cannot further simplify 10. So, we have:

Our answer is thus A.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
