8-5 = 3, 6-4 = 2
so the sides of triangle are 3 and 2, now using the formula 1/2 *a * b
we get 3*2/2 = 3
The answer is 45

Answer:
R = 20
Step-by-step explanation:
mean age = sum of ages/no. of men
sum of ages of the men that left = 55 + 63 = 188
remaining sum = 50R - 118
remaining no. of men = R - 2
now mean age = 50 - 1 = 49 years
49 = 50R-118/R-2
49(R - 2) = 50R - 118
49R - 50R = -188 - 98
-R = -20
R = 20
Let's assume we were given 2 numbers: 15 and 30. Their sum is:
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
In this case sum of two numbers can always be written as:
