The quadratic equation could be:
To solve this, plug in 8 for X
3+9(8-1) then solve
3+9(7)
3+63
66
I hope I've helped!
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
Three quarters
one ten
one five
three pennies
