dividing with the same numbers and different exponents is like subtracting the exponents
16-8 = 8
I thick it's c but please don't put it if it is wrong
6x=10^= (*=0) is the answer
Lilla got 21/25 meaning she only missed 4 questions which means she got a 96/100. Tim scored 41/50 meaning he missed 9 questions meaning he got a 91/100 therefore being the reason Lilla got a higher score than Tim being that she has a 96 versus his 91. Hope that helps!!!
Height of the trapezoids = sqrt (17^2 - 8^2) = 15cms
base = 19 cms
(b) area of each trapezoid = 15/2 (35 + 19) = 405 cm^2
Total area painted blue = 2*405 = 810 cm^2
(c) length of the edges of one trapezoid = 35 + 19 + 2(17) = 88 cms
So one piece of sandpaper ( can sand up to 80 cm) will not be enough to sand all of the edges.
