gcf(10x8, 15x6) = 5x6
15x
25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks
In simple terms: 68-10x
It is: -5x-20 when simplified
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
5x^3(3x + 2)
the lens at the top that you look through.they are usually 10x or 15x power
5x-15x+10 = 10-10x when simplified Assuming a request to solve the equation: 5x -15x + 10 = 0 5x - 15x + 10 = 0 5x - 15x = -10 or (multiplying everything by -1 gives you -5x + 15x = 10) so 15x - 5x = 10 10x = 10 x =1
15x
15x-20y= 7 5y-3 +10x
5x +12 = -78 -10x +10x +10x 15x +12 = -78 -12 -12 15x = -66 /15 /15 x = 4.4
5x + 10x doesn't need factorization as you can just add them up (5x+10x=15x). However, if you really want to, 5x+10x=5x(1+2)=5x(3)=15x
There is some kind of formula here, half angle, or some such that I forget, but I do remember the algorithm. So...,int[cos(10X)cos(15X)] dxsince this is multiplicative, switch it aroundint[cos(15X)cos(10X)] dxint[cos(15X - 10X)/2(15 -10) + cos(15X + 10X)/2(15 + 10)] dxint[cos(5X)/10 + cos(25X)/50] dx= 1/10sin(5X) + 1/50sin(25X) + C=========================
The power of a microscope magnification is the eye piece power times the objective lens so 10X eye piece times 10X objective is 100 power Common eyepieces are 10x 15x, 20X. The limit is about 2000X in an excellent unit. Average practical use is about 1000X to 1400X In expensive scopes the higher power objective lenes as 100X are made from oil not glass.
