A wooden panel is a parallelogram with a height that measures 3x + 1 cm and a base that measures 4x - 2 cm. (View attachment) a) How muich paint will you need to paint both sides of the panel? Write your answer as a simplified polynomial.
b) If x = 7 cm, how many cm² of paint will you use?

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
