Answer: 220 cm squared
Step-by-step explanation: Formula for surface area of a prism...
S = 2(lw + lh + wh) l = 5 w = 10 h = 4
so
lw is 5 x 10 = 50
lh is 5 x 4 = 20
wh is 10 x 4 = 40
plug these into equation...
S = 2(50 + 20 + 40)
S = 2(110)
S = 220
Answer:
The answer is a = 1/4 , b = 0 and c = 5
Step-by-step explanation:
∵ 1/4 x² + 5 = 0 is a quadratic equation
∵ ax² + bx + c = 0 is the general form of the quadratic equation
∴ a = 1/4
∴ b = 0
∴ c = 5

Answer:
The total bill is $99.60
Step-by-step explanation:
First simplify inside parenthasees
8-6x+12
-6x+8+12
-6x+20
distributive poproty
a(b+c)=ab+ac
1/4(-6x+20)=-6x/4+20/4=
-3/2x+5
