Answer:
106
Step-by-step explanation:
Ok this question is a bit confusing but once you understand the concept you will be able to answer the question correctly
Always know that bracket is solved first once it is found in the question
So back to the question
-4(2-5)2+82
So let's get to work...
Bracket first
-4(-3)2+82
Multiply with the number at the front then followed by the one at the back
(+12)2+82
24+82
106
Therefore the final answer is 106
I believe you understand how we get the answer...just be careful when solving this kind of question... simple
Answer:
The value of f(3) = 13
Step-by-step explanation:
It is given that a function f(x),
f(x) = 2x²/2 + 4
<u>To find the value f(3)</u>
For that we have to substitute 3 instead of x
f(x) = 2x²/2 + 4
f(3) = 2 * (3)²/2 + 4
= (2 * 9/2 )+ 4 = 13
Therefore the value of f(3) = 13
consecutive integers have a difference of 1 between them
let the brothers have ages n , n + 1 and n + 2 thus
n + n + 1 + n + 2 = 96
3n + 3 = 96
subtract 3 from both sides of the equation
3n = 96 - 3 = 93
divide both sides by 3
n = 
= 31
The ages are 31 , 32 and 33
A= 10
subtract 4 from both sides to get “a” by itself.
