Answer:
105 cm²
Step-by-step explanation:
We can see that the area at the square at the bottom, since one side is 5, is 5²=25. Then, we know that the height of the triangles is 8, the base is 5, and there are 4 of them, so ((5*8)/2)*4=80. Add these up to get 105 as our total
I got 75582.
Explanation:
First, group the 40 identical candies into 20 pairs. It doesn't matter how since the candies are identical. This grouping will ensure that any assigment will contain at least two candies.
Then think of the 20 groups a 20 beads on a string. We are looking to place 11 separators between them to obtain 12 segments, each with a varying number of beads between them. How many ways are there to place 11 separators to 19 potential spaces between beads? The asnwer is 
Answer:
56x+21
Step-by-step explanation:
7times 8x is 56x
7 times 3 is 21
add them together and you get 56x+21
Answer:
e ≥ 2w
Step-by-step explanation:
To make this easier, let us consider the case of Eliza being exactly twice as old as wendy
that would mean that twice the age of Wendy is the age of Eliza
e = 2w
but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy
Hence, the symbol '=' will be replaced by '≥'
Hence, the correct relation is
e ≥ 2w
