1.) Factor 9u^2-12u
2.) Cancel any common factors (in bold will be the terms eliminated)
Final answer is:
3u-4
Therefore, the answer is
C. 3u-4
You required to find the value of d.
Always remember the concept that if you transpose "+" sign to the other side, it becomes "-" sign, and vice versa. Make sure that you arrange the like terms and constants. Solving the equation,
6d + 1 = 15 - d
6d + d = 15 - 1
7d = 14
d = 14/7 = 2
When transposing a multiplication, you divide it to the other side.
Verifying the solution,
6(2) + 1 = 15 - 2
12 + 1 = 13
13 = 13
I would say 12 I could be wrong though
In this item, we have:
A = 6x² + x +3
h = 3x
where ''A'' is area and ''h'' is height. From the statement above,
length of base, b = A / h
<em> b = (6x² + x + 3)/3x
</em>
Thus, the expression for the length of the base is 6x²+x+3 / 3x.
