9 - (a - 7)
Note that - = -1
First, distribute - 1 to all terms within the parenthesis
-1(a - 7) = -a + 7
9 - a + 7
Combine like terms
9 + 7 = 16
-a + 16, or A. 16 - a is your answer
hope this helps

Answer:
133
Step-by-step explanation:
Answer is 133
Okay, we know that the expenses for the day is 210.
Knowing this, and the price of the taco, we write the inequality:
3.25t > 210
t = number of tacos
Now divide both sides by 3.25:
t > 64.62 (rounded)
Because a taco stand can't sell a fraction of a taco, we know that the taco stand has to sell more than 65 tacos for a profit.
I have to assume that you mean it is a similar rectangle, since a triangle can not be similar to a rectangle. In that case the original measurements are 4x4.5.
By doubling them, you get a rectangle with the measurements of 8x9 and thus the area is 72
