Please help :/ i don’t understand. konnor was curious if quadrilaterals STUV and WXYZ were similar so he considered their angles Konnor concluded: “The quadrilaterals have four pairs of congruent corresponding angels, so the figures are similar”.
A. the quadrilaterals are congruent, not similar.
B. it’s impossible to map STUV onto WXYZ using only rigid transformations and dilation s so the figures are not similar
C. there are no errors this is a correct conclusion.

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
