If s(x) = x-7 and t(x) = 4x-x+3, which expression is equivalent to (t• s)(x)? O 40x-7² -x-7+3
O 4(x-7) -x-7)+3
O (4x-x+ 3)-7
O (4x-x+ 3)(x-7)

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
