Eliminating parentheses gives
10.5u -18 = 8.25
10.5u = 26.25
u = 2.5
The value of u is 2.5.

What fun! Michael spent 2.5 hours walking up the hill for 0.5 hour of time sledding down.
Okay follow these patterns and you will always get your answer
Cone = (13)πr2h, where r is the radius and h is the height.
Cube = s2, where s is the length of the side.
Cylinder = πr2h, where r is the radius and h is the height.
Rectangular prism= l×w×h, where l is the length, w is the width and h is the height.
Sphere = (43)πr3, where r is the radius.
ANSWER: (D) 904.78 cm^3
Step-by-step explanation:
the area is
length × width
(3x - 2) × width = 9x² - 4
to find width we could do a real polynomial division or simply recognize the fact that
(a + b)(a - b) = a² - b²
and we see that in our area calculation we are missing the (a + b) factor.
so, width = (3x + 2)
but if you want the division :
9x² - 4 : 3x - 2 = 3x + 2
- 9x² - 6x
-----------------
0 6x - 4
- 6x - 4
----------------------
0 0
again, width = (3x + 2)
Yes he is correcct because 4/8 and 1/2 is the same thing
