Exercise: evaluate the expressions for a = 2 and b = 6
(a + b)2

16

Step-by-step explanation:

Simply plug in 2 for a, then 6 for b and substitute

(2+6)2

Then do order of operations to simplify PEMDAS

First what's inside the parenthesis

(8)2

Then multiply

16.

16

Step-by-step explanation:

(2+6)2

2 TIMES 6 = 12

2 TIMES 2 = 4

12+4=16

true? is that what you're asking or do you mean something else?

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
