Which equation has an a-value of 1, a b-value of –3, and a c-value of –5?

Step-by-step explanation: (x-1) (x+3) (x+5) = 0

       (+2x-3) (x+5) = 0

   (+7+7x-15=0

∵ Equation has three values or roots

∴ It's degree should be three (degree - highest power of variable)

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

the surface area is 124cm²
