I hope this helps you
First we need to find the base using Pythagoras:
5²-3²=b²
25-9=b²
16=b²
√16=b
4=b

Now we use the equation to find the area of a triangle:
bh/2
(4*3)/2
12/2
6

The answer is 6

Hope this helps :)

45 less than twice the number of n

Answers

n = 15

What are arithmetic operations?

Use one of the four fundamental arithmetic operations to add, subtract, multiply, or divide two or more integers. For challenging computations, we use the PEMDAS approach.

Given five times n is equals to 45 less than twice the number of n.

hence,

5 * n = 2* n + 45

3* n = 45

n = 15

Therefore the value of the n in the given problem is 15.
