The first thing you need to do is in parenthasis. 37+8=45. Now 45-15=30.
From the middle of the hexagon to one of its edges will be 4.A hexagon can be formed from 6 equilateral trianglesThe area of one equilateral triangle in this case is:A=bh/2A=4(sin60*2)A=8sin(60) A of hexagon = 8 * 6sin(60)=16√3
P = 4*6 = 24
On the right side of the equation, when the student combined like terms, 7x and -4x, they did not combine them correctly. Instead of combining them correctly, the student forgot to include the sign of the -4x which caused the sum of the two terms to be 11x instead of 3x. Hope this helps!
Lets convert the fraction first to ease the calculations:
2 5/8 = 16/8 + 5/8 = 21/8
so now we can operate easily, to calculate we need to multiply 21/8 by 2/3 that is because, if 1/3 is used then 2/3 are left over (1/3 + 2/3 = 1, the total), so we have:
(2/3)(21/8) = (2*21)/(3*8)
= 42/24
= 21/12
= 7/4
so 7/4 are left over
If you just want to know what is the greatest common factor of 24 and 54, it is 6. Usually, this is written as
gcf(24,54) = 6
