5 because 4x5 = 20 and also 3x6= 18 but add another because 18 dont fill the pounds of plaster
Answer:
C. a = 3
b = 7
c = -20
Step-by-step explanation:
x = -b+/- (sq) b^2 - 4ac.
Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0
S if you use your equation : 3x^2 = 20 - 7x
First you have to move everything to one side.
So it'll look like this:
3x^2 = 20 - 7x
-20 -20
3x^2 - 20 = -7x
+7x +7x
3x^2 - 20 + 7x = 0
don't forget that... Ax^2 +Bx+ C= 0
3 = A
7 = B
-20 = C
Answer:
Step-by-step explanation:
Additional fee per person = $3
Additional fee for 's' person = 3*s = 3s
C = 60 + 3s
Answer:
