Answer:
Step-by-step explanation:
Surface area = lateral area + 2(area of base)
Lateral area = perimeter of base * height.
Because it is a isosceles right triangle, both sides are equal.
= 72
2
= 72. Divide both sides by 2
= 36. Square both sides.
x = 6.
So the perimeter of the base = 6 + 6 +
= 20.485281374239
Lateral area = 20.485281374239 * 7 = 143.397 
Area of base is (1/2)base * height.
(1/2)(6)(6) = 18
Using the surface area formula
surface area = 143.397 + 2(18) = 179.4 
Answer:
52
Step-by-step explanation 1/3 i believe it would be 1/6 of 314 which would be 52 and 1/3.
Answer:

Step-by-step explanation:
Let's use a start by using common denominators.
and 
Now, replace the original equation with the common denominators. 
Solve! 
The answer is 0, as there is no slope going up or down.
