Larger by 3 means that the legnths of the sides are larger by 3 times
so we have a cube that has area of 400
surface area=legnth times width times 6 since it is a cube and legnth=width
so
SA=w^2 times 6
6w^2=400
divide by 6
w^2=200/3
square root both sides
w=√(200/3)
so w is 3 times larger
(3w)^2 times 6 is new area
w=√(200/3)
(3√(200/3))^2 times 6=9(200/3) times 6=600 times 6=3600
answer is 3600 ml^2
THE MEDIAN IS THE MIDDLE NUMBER IS 86 AND 90
Just place dots where the points are saying, the first number is always x aka the horizontal line ( the one that is going down) and the second number is y aka the vertical line ( the one going up)
Answer:
216
Step-by-step explanation:
Total of octagon amount is 1080, so set it equal.
x + 2x + 3x + 4x + 6x + 7x + 8x + 9x = 1080
45x = 1080
/45 /45
x = 24
Then plug in for largest number.
9 (24) = 216
B = 7/8(A-9)
first you must distribute
B = 7/8A -7 7/8
add over the -7 7/8
B + 7 7/8 = 7/8A
now divide both sides by 7/8
B+7 7/8
----------- = A
7/8
