Answer:
B.
Step-by-step explanation:
b is a long vector directed to the upper right. 1/3 of that will be a short vector (1/3 the length of b). When it is subtracted, its opposite is added. The vector diagram showing the subtraction will have a shorter vector directed to the lower left. Its tail will be at the nose of 2a. Only diagram B fits this description.
13 2/3

The answer is

The expression is:

Let's factorize it:

Since

, then:

Cancel x(x-3) and simplify:
Multiply each of the fractions by 1 to get them to have the same denominator.
1/4 x 3/3 = 3/12
1/3 x 4/4 = 4/12
New Equation:
3/12a + 4/12a + 8 = 22
now add up similar terms
7/12a + 8 = 22
subtract 8
7/12a = 14
multiply each side by your denominator
12(7/12)a=12(14)
7a=168
divide by 7
a = 24
