Find the surface area of the prism please help fast

17.6 squared feet

Step-by-step explanation:

triangle is 0.5 X b X h

0.5 X 1 X 2 = 1 squared foot.

(there are two triangles) 1 X 2 = 2 squared foot

rectangle sides

2.2 X 3 = 6.6

1 X 3 = 3

2 X 3 = 6

add them altogether

2 + 6.6 + 3 + 6 = 17.6

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

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
