Let p represent: A polygon has three sides. • Let q represent: A polygon is a triangle. What is the verbal expression of the following statement? Statement: p~ O A polygon does not have three sides if and only if it is a triangle. O A polygon has three sides if and only if it is a triangle o If a polygon does not have three sides, then it is a triangle. A polygon does not have three sides if and only if it is not a triangle.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is 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

d. you cannot tell because there are no values shown.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
