What is the area of the combined rectangle below? 20yd would be the base, 12yd would be the base, 5yd would be the height, 3yd would be the height. (a) 136 square yards ? (b) 100 square yards? (c) 76 square yards? (d) 64 square yards?

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

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

Ineed with angles and the measure of them i have abc a is 65 and b is (3x-10) and c is (2x) find the value of x
