Students were asked to write a formula for the length of a rectangle by using the formula for its perimeter, p = 2 + 2w. Three of their

responses are shown below.

1. f = p - w

II. t = 3(p – 20)

III (= =24

Which responses are correct?

I and II

II and III

I and III

I, II, and III

"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

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically

55 degrees because 55+55=110 degrees

cluster sampling.
