Answer: x^2 - 8x + 16
Let y = x-4
(x-4)^2 = (x-4)*(x-4)
(x-4)^2 = y*(x-4) ... replace one copy of (x-4) with y
(x-4)^2 = x*y - 4*y .... distribute
(x-4)^2 = x*( y ) - 4( y )
(x-4)^2 = x(x - 4) - 4(x - 4) ... replace y with x-4
(x-4)^2 = x^2-4x-4x+16 .... distribute
(x-4)^2 = x^2 - 8x + 16
20.30 x .65 + answer. 13.195 + 20.30= 33.495 or 33.50
25000=X [((1-(1+0.078)^(-5))/0.078]
Solve for x
X=6228.44
Answer: 1.1 x 
kg
Step-by-step explanation:
Mass of Venus = 4.87 x
Mass 0f Earth = 5.97 x
The difference in mass implies :
5.97 x - 4.87 x
= 1.1 x
Step-by-step explanation:
You can let me know, but i dont think -3x² is supposed to be squared in this question because then it would make it unsolvable.
5x-15
can be simplified to 5(x-3)
x²-3x
can be simplified to x(x-3)
Then u rewrite it (5 + x)(x - 3)
