*Please help asap taking a test!* (Thank you!) :D Max saw the following problem: 3 · (3 + 12 ÷ 3) - 4 The first thing he did was add 3 + 12 to get 15. What is Max's error?

-He should have multiplied 3 · 3 first
-He should have subtracted the 4 first
-He should have divided 12 ÷ 3 first
-He did the correct thing first

Can someone me with this problem . show your work .

In the following diagram it is given that dec, ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Two line segments are shown in the figure below. suppose that the length of the line along the x-axis is 6, and the length of the hypotenuse of the triangle is 10. what is the equation of the hypotenuse line (shown in red, below)?
