Based only on the info in the diagram, which congruence theorems or postulates could be given as reasons why ∆CDE = ∆OPQ? Check all that apply.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

the answer is:

mean: 6

mad: 2.14

"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
