The answer for this problem is 4
A /3 + (a - 2) / 4 = 8
multiply through by 12:-
4a + 3(a - 2) = 96
7a = 102
a = 14.57 to nearest hundredth
3.4x - 7.2 = 5.8x + 24
3.4 - 5.8x = 24 + 7.2
-2.4x = 31.2
-2.4x / -2.4 = 31.2 / -2.4
x = -13
Answer:
Let y=x² . Then:
x4−10x2+9=y2−10y+9
y²-10y+9=(y-9)(y-1)
Substitute x² for y:
x4−10x2+9=(x2−9)(x2−1)
x²-9=(x+3)(x-3)
x²-1=(x+1)(x-1)
x4−10x2+9=(x+3)(x−3)(x+1)(x−1)
(2p + 7)(3p-9)
2p x 3p= 6p^2
2p x -9= -18p
7 x 3p=21p
7 x -9=-63
6p^2 - 18p + 21p - 63
6p^2 + 3p -63 is the answer.
