Take 22 * 23 and it is equal to 506
Given
in ∆ABC
AB = 5cm
BC = 6 cm
AC = 7 cm
now,
as we have to make ∆PQR inside it
than, possibly ∆PQR's sides length is,
PQ = ½ of CB (according to mid point theorem)
→ CB = 6cm → 6/2 → 3cm
PQ = 3cm
QR = ½ of AC
→ AC/2 = 7/2 = 3.5 cm
RP = ½ of AB
→ AB/2 = 5/2 = 2.5cm
therefore, length of
PQ = 3cm
QR = 3.5 cm
PR = 2.5 cm
Hope this answer helps you dear!
Answer:
Step-by-step explanation:
The sum of a number and 9 is adding of any variable to 9.
E.g the sum of 8 and 7
8+7=15
We can also have the sum of two unknown numbers, we can let the first number be x and the second number be y, then the sum of the two unknown will be (x+y).
So, let apply this to the question
The sum of a number and 9, since we don't the number, let the number be n, then the sum of the number and 9 will be (n+9)
Then the correct option is B which is n+9
