Answer:
4(2qp + 5qr - 4s)
Step-by-step explanation:
8pq + 20qr – 16s
we can use 4 as a common factor between these numbers.
8/4 = 2
20/4 = 5
16/4 = 4
so
4(2qp + 5qr - 4s) is the most factorized answer we can get
We are asked to evaluate the given expression 3 (r² + t) - r² given that r is equivalent to 2 and t is equivalent to 7. The solution to this problem is shown below:
3 (r² + t) - r² , substitute r=2 and t=7 in the expression
3 (2² + 7) - 2² , perform squared
3 (4+7) -4, perform addition of 4 and 7
3 (11) -4, perform multiplication os 3 and 11
33 - 4, perform subtraction
29
The answer is 29.
