What is the simplified form of the quantity of x plus 5, all over the quantity of 3x plus 4 + the quantity of x plus 4, all over
the quantity of x plus 3?
the quantity of 2x plus 9, all over the quantity of 4x plus 7
the quantity of 4x squared plus 24x plus 31, all over the quantity of 3x squared plus 13x plus 12
the quantity of 4x squared plus 24x plus 31, all over the quantity of 4x plus 7
the quantity of 2x plus 9, all over the quantity of 3x squared plus 13x plus 12
1 answer:
(x + 5) / (3x + 4) + (x + 4) / (x + 3)
[(x + 5)(x + 3) + (x + 4)(3x + 4)] / (3x + 4)(x + 3)
(x² + 8x + 15 + 3x² + 16x + 16) / (3x² + 13x + 12)
(4x² + 24x + 31) / (3x² + 13² + 12)
The first option is correct.

Answer:
P'(-12,8)
R'(-1, 1/2)
Q'(9, -9/2)
1 1/3. One whole number is 3/3 so 3/3=1 then u put 1/3
Eight below zero would express the value -8, negative eight,
but not 8.
W+D=659
W=D-91
---------------------------
(D-91)+D=659
D-91+D=659
2D=750
D=750/2=375
------------------------------
W+375=659
W=284
------------------------------
So the dryer had cost $375 and the washer had cost $284.
d²-12=0
d²=12
d=√12
d=3.46..
Hope it helps! :)
