John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $3.40 plus $2 per mile. The total fare was $9.40, not including the tip. Which
equation or tape diagram could be used to represent the context if x represents the
number of miles in the taxi ride?

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
