#40 is $110.16 total.  You have to add the sales tax to the amount of the baseball cap which comes to $13.77.  Then take that amount and multiply by the number of caps.  Hope this helps.

38a) $10.50 To get this answer, you need to multiply $1.50 by 7

38b) $25.50 To get this answer, you need to subtract $10.50 from $36

40) The answer would be $13.7694 and it could be rounded to $13.77. To get this answer .you need to multiply $12.99 by 1.06 since it has a 6% sales tax.

Pls help
solong [7]
Ok let’s solve it

5(x-2)^2-20=0

first let’s foil (x-2)

5(x^2-4x+4) -20=0

now distribute the 5

5x^2 -20x +20 -20 = 0

combine like terms

5x^2-20x=0

take the gcf

5x(x-4)=0

x=0, 4

solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
