Answer:
B
Step-by-step explanation:
Consider this:
Cheese Dip --> Burrito --> Chicken
Cheese Dip --> Burrito --> Beef
Assume Cheese Dip is your starting point and Chicken / Beef are your ending points. We already have two combos here.
Now looking at the diagram, we should see eight ending points in total.
Therefore, there would be eight combinations for Lelia to choose.
Answer:
x = 39
Step-by-step explanation:
We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:
80^2 + x^2 = 89^2
6400 +x^2 = 7921
x^2 = 1521
x =
x = 39

2² simplified means 2 times 2 (2 times itself) so
2² = 4
2×2=4
2²=4
Now , it doesn't make any difference with a number like 2 .
Suppose we had 3 :
3² = 9
3² is not the same as 3 ×2 , and here's the reason for that :
3²=3×3=9
3 × 2 = 6

Let the height of prism be

As it is twice the width, width is
