Answer:he would have to pay with three 20 dollar bills
Step-by-step explanation:
pizza = $10
sub = $5
soda = $1
3 x 10 = $30
4 x 5 = $20 $30 + $20 = $50
8 x 1 = 8 $50 + $8 = $58
sale tax = 7.5
58 + 7.5 = 65.5
Answer:
x^2 - 4x + 29 = 0
Step-by-step explanation:
Complex roots occur as conjugate pairs.
So the other root will be 2 - 5i.
First write the equation it in factor form:-
(x - (2 + 5i)) (x - (2 - 5i) = 0
(x - 2 - 5i)(x - 2 + 5i) = 0 Now expand:-
x^2 - 2x + 5ix - 2x + 4 - 10i - 5ix + 10i - 25i^2 = 0
x^2 -2x - 2x + 4 - 25*-1 = 0
x^2 - 4x + 29 = 0 (answer)
