A box contains 7 black shirts, 9 blue shirts, 11 black pants, and 13 blue pants. Determine the probability of randomly selecting a black piece of clothing or a pair of pants. Use PIA or B) = P(A) - P(B) - P(A and B) to
explain your answer.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

the answer is -1 1/5, also a
