ayus lng ako hahaha hshshs
The answer is
X= -3/2 or x=1
Volume= area of base x height
base= 3.14 x 4^2(8/2=4 for the radius)
base=50.24
base x height=50.24 x 23=1155.52, or 1156 ft3
If she answered all then she would have gotten 179 wrong. If I understand 200 questions and 11% on the test then 179 wrong and 21 right. So if you are asking how many she did not answer I would assume the questions she got wrong were the questions she did not answer which would be 179.
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132
