Ahospital needs a circular landing pad for their helicopter. the landing pad should be 5000 square feet. the contractor calculated that the pad would need to be about 40 feet across

area = pi x r^2

5000 = 3.14 x r^2

r^2=5000/3.14 = 1592.356

 r = sqrt(1592.356) = 39.9 round to 40

 diameter = 40*2 = 80

 the pad needs to be 80 feet across

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
