Consider a triangular prism. the triangular end has a base of 4 cm and height of 5 cm. the length of each side is 6 cm and the height of the prism (length of the rectangle) is 10 cm. what is the surface area of this triangular prism? a) 120 cm2 b) 180 cm2 c) 190 cm2 d) 200 cm2

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

can you put the picture up?
