A trapezoid has bases of lengths 40 and 42. Find the trapezoid's height if its area is 820 ​

Height = 20

Step-by-step explanation:

trapezoid area = (Sum of bases x height) / 2

((40 + 42) x h ) / 2 = 820

82 x h = 1640

h = 20

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
