Evaluate the following using the order of operations. 17 – 4 • 3 + 18 3(4) + 4(5) (60 – 20) ÷ 4 + (3 • 5) 15 – 2 • 4 – (6 – 3) (3 • 2 + 6) ÷ 4 + 2(18 – 3) 25 + 10 – 5 ÷ 5

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

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

What are the solutions of the following system? y=-2x^2 y=x-2
