Find the total surface area of the shape
Rina8888 [55]

Answer:

510 ft²

Step-by-step explanation:

in the triangle

base (b) = 5 ft

height of the triangle (h1) = 12 ft

height of the prism = 15 ft

Now

Lateral surface area (LSA)

= perimeter of triangular base * height

= ( 13 + 5 + 12) * 15

= 450 ft²

Total surface area

= LSA + 2 * area of triangular base

= 450 + 2 * 1 / 2 * b * h1

= 450 + 5 * 12

= 450 + 60

= 510 ft²

Hope it will help :)❤

Solve the following equation <br><br> 1/x-1+1/x+2=3
disa [49]

Answer:

x = 1

Step-by-step explanation:

Solve for x over the real numbers:

-1 + 2 + 1/x + 1/x = 3

-1 + 2 + 1/x + 1/x = 1 + 2/x:

1 + 2/x = 3

Bring 1 + 2/x together using the common denominator x:

(x + 2)/x = 3

Multiply both sides by x:

x + 2 = 3 x

Subtract 3 x + 2 from both sides:

-2 x = -2

Divide both sides by -2:

Answer:  x = 1
