This is a problem of Permutations. We have 3 cases depending on the number of B's. Since no more than three B's can be used we can use either one, two or three B's at a time.
Case 1: Five A's and One B
Total number of letters = 6
Total number of words possible = 
Case 2: Five A's and Two B's
Total number of letters = 7
Total number of words possible = 
Case 3: Five A's and Three B's
Total number of letters = 8
Total number of words possible = 
Total number of possible words will be the sum of all three cases.
Therefore, the total number of words that can be written using exactly five A's and no more than three B's (and no other letters) are 6 + 21 + 56 = 83

Answer: Length because A unit of length refers to any arbitrarily chosen and accepted reference standard for measurement of length.
Answer:
The heigh of the triangle is 10cm
Step-by-step explanation:
The area of a triangle is given by the formula A=1/2bh where
A = the area of the triangle,
b = the length of the base, and
h = the height of the triangle.
To find the height when
the
Area of the triangle, A =45cm2,
base of the triangle, = 9 cm long.
Using the formula, A = 1/2 × b × h
45 = 1/2 × 9 × h
Cross multiplying
2×45 = 1×9×h
90 = 9h
h = 90/9 = 10cm
