Answer:
Step-by-step explanation:
Prime factorize the given number. All factors should have pair. If all factors have pair, then it is a perfect square
EG: 36 : Factors of 36 are 2,3,2,3. Here there are two 2's and two 3's. so 36 is a perfect square.
EG: 24: Factors of 12 are 2,2,3. Here 3 is without pair. so it is not a perfect square.
The base price of the iphone is $350 and additiobal charge of a month is $67. So additional charge for p months is $67p.
Determine the equation for total cost of iphone after p momths.
Do it both side +5 . Then that 23 will be 28.so the question will be 4a=28.
then diveded by 4 both side.
A will be 7.
Your answer is "7"
28÷4=7 ^^
