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
If you divide 36 by 4, it equals 9, so each side is 9. Then you multiply 9 to 9, which equals 81 in^2.
Answer:
58.5
Step-by-step explanation:
This expression should be simplified using order of operations. According to order of operations or PEMDAS, complete any numbers in parenthesis then any exponents, multiplication, division, additions and subtraction moving left to right through each operation.
Begin with Parenthesis.
(7+3-4*9) - Multiply first
(7+3-36) - Then add/subtract left to right
10 - 36 = -26
Replace -26 where the parenthesis were in the original expression.
9/4 (-26)
234/4
58.5
