So you first have to draw a line down the middle through the = then subtract either 2x or 3x (I did 2x) on both sides and that should give you 1x+3=12. then I subtracted 3 from the twelve and that gave me 1x=9 and then you divide 1 on each side (which crosses out the x) and so the answer that I got was x=9!
Answer:
x=2. or. x=8
Step-by-step explanation:
x^2-10x+16=0. s=-10
x^2-8x-2x+16=0. p=16
x(x-8)-2(x-8)=0. [-8,-2]
(x-2)(x-8)
x=2. or. x=8
Answer:
0.7999989281
Step-by-step explanation:
x1 = cos^-1 (3/5)
x1= 53.13°
sin(53.13) = 0.7999989281
