Can you insert a photo lol
Answer:correct answer =0
Step-by-step explanation:
Step 1
5x - (x + 3)2
Putting the coefficient of x =2 in the equaton we have
5(2) - (2 + 3)2
Solving out
5(2) - (5)2
= 10- 10
=0
Step 2
Amir's mistake was in the multiplication and wrong use of the negative sign of the bolded below
5(2) - (2 + 3)2 = 10 + (-5)2 = 10 + 25 = 35
-(5)2 cannot give 25 instead 10, so him getting a 25 and wrong use of the negative and positive made his answer wrong.
The right answer as calculated in step 1 = 0
When you distribute you get 12x-24-7x=-80
when you combine like terms you get 5x=-56
answer : x = -11.2
Dimensions possible are:
80x1
40x2
20x4
10x8
5x16
The dimension that makes most sense is the 5 by 16 for a pot holder.
The odd numbers in between those two numbers are: 23, 25, 27, 29, 31, 33, 35, and 37. When you add them all up, you get an answer of: 240.
If you are including those two numbers, the answer would be: 300
Hope this helps!
