Can someone me with number 6 and number 7 you

For number 6

a) You can circle 4 right angles, 2 pairs of parallel sides, and all sides equal.

b) you could circle only one pair of parallel sides.

for 7 the answer is 405. Just times 15 by 27

Hope this helps!

brainliest answer? :)

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
