In right △ABC , the right angle is at C, m∠A=30∘ , and AC=7√5 units.

What is the perimeter of △ABC ?

7√15 + 7√5 units

(7√15 + 14√5)/2 units

(14√15 + 7√5)/2 units

21√15 + 7√5 units

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
