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 :)❤

Step-by-step explanation:
the intersection of the interval: (-∞, 7) and [-5, +∞)
is [-5, 7)
and the union of the interval: (-∞, 7) and [-5, +∞)
is (-oo, +oo)
Answer:
x= 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1x+3=x+10x−2
x+3=x+10x+−2
x+3=(x+10x)+(−2)(Combine Like Terms)
x+3=11x+−2
x+3=11x−2
Step 2: Subtract 11x from both sides.
x+3−11x=11x−2−11x
−10x+3=−2
Step 3: Subtract 3 from both sides.
−10x+3−3=−2−3
−10x=−5
Step 4: Divide both sides by -10.
−10x/−10=−5/−10x=1/2
