2(3x-1)=8x-20
SIMPLY
6x-2=8x-20
SUBTRACT 6x ON BOTH SIDES
-2=2x-20
ADD 20 TO BOTH SIDES
18=2x
DIVIDE 2 ON BOTH SIDES
X=9
SUBSTITUTE
3(9)-1
27-1
26
BC=26
(5 1/4 in)(12 1/2 in)(4 in)
(21/4)(25/2)4=262.5 in^3
Answer:
36
Step-by-step explanation:44-8=36
Question 1- A circle is formed from the cross section of a plane and sphere
Question 2- A square is formed from the cross section of a plane and a cube
Question 3- A circle is formed from the cross section of a plane and cone
Question 4- A rectangle is formed from the cross section of a plane and rectangular pyramid.
Question 5- A circle is formed from the cross section of a plane and a cylinder
Triangle HAM looks like an isosceles triangle, and we know that in an isosceles triangle 2 of the angles are the same.
so :
180 - 106 = 74 ( sum of the other 2 angles )
74/2 = 37 ( sum of angle HMA / HAM )
angles on a straight line add up to 180.
180-37=143 ( angle x )
since triangle YMH is also an isosceles,
180-37=143
143/2=71.5 ( angle w )
