Elena gives the following sequence of transformations to show that the two figures are similar by transforming ABCD into EFGD. Elena says to:

1. Dilate using center D and scale factor 2.

2. Reflect using the line AE.

Looking at the diagram below, is Elena’s method correct? If not, explain how you could fix it.

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality

Rewrite the expression in z to the n power. the expression i was given is: 1 over z to the negative 1 half power.
