Is there a math question and can you show it please
Answer:
Kenny is 18 years old Andrew is 10 years old Tim is 30 years old and Cameron is 5 years old
Step-by-step explanation:
Let a be Kenny's age , b be Andrew's age , c be Tim's age , d be Cameron's age
( b < a , b<c , d<b)
Kenny is 8 years older than Andrewn = > a = b + 8 (1)
Tim is 3 times as old as Andrew => c = 3 . b (2)
Cameron is 5 years younger than Andrew => d = b-5 (3)
The combined age of the four is 63 => a+b+c+d = 63 (4)
(1),(2),(3),(4) => b+8 + b + 3b + b-5 = 63 <=> 6b + 3 = 63 <=> b = 10
=> a= 10+8 =18, c = 3 . 10 = 30, d= 5
Answer:
The first blank is 81
+9=x-1
The second blank is 9x+3=x^2-1
Step-by-step explanation:
For the first part, you must set up the equation (9x+3)^2 then you must multiply the exponent to the inside exponents
+
next, simplify.
81
+9=x-1
For part two, set up equation.
Then simplify 9x+3=
