Step-by-step explanation:
Volume of a cylinder : πr^2*height.
Volume : 150cm^3
height : 7.2m
π =3.14
150 = 3.14*r*r*7.2
150=22.608*r*r
r^2= 150/22.608
=150/23cm^2
r=√6.5
r=2.569cm
r=2.6cm
Answer:
D. 14.73
Step-by-step explanation:
According to Pythagoras,
19^2 = 12^2 + x^2
x^2 = 19^2 - 12^2
x^2 = 361 - 144
x^2 = 217
x = 
x = 14.73
Not sure what algebra tiles are
not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x
remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x
If this is a True or False question, that is true.
