If it is isosceles, than the legs are the same. We will call them X. The formula for the area of a triangle is 1/2 (base * height). But the base and the height are both X. So the area (18) is equal to 1/2 (x * x), or 1/2(x^2). This means that 36 = x^2. Thus, the length of each side is 6 inches. You can check this work by plugging those into the formula for area. You will find that it equals 18.

Step-by-step explanation:
f(x) = 9 * 81^x
When x = -1/2,
f(-1/2) = 9 * 81^(-1/2) = 9 * (1/9) = 1.
Answer:
Difference is 14,787 ft
Step-by-step explanation:
Mt. Whitney = 14,505 ft above sea level
sea level = 0 ft
Death Valley = below sea leve
14505 - (-282) = 14787 ft
The cups of milk Laura gave to Maria is 19/12 cups is 19/12 cups
<h3>How to calculate fraction</h3>
- Total cups of milk to share = 2 1/4 cups
Total = Laura + Maria
2 1/4 = x + 2/3
2 1/4 - 2/3 = x
9/4 - 2/3 = x
(27-8) / 12 = x
19/12 = x
= 1 7/12
Therefore, the cups of milk Laura gave to Maria is 19/12 cups
