Answer:
48:26.075
Step-by-step explanation:
The value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The expression is:
= 13(a×b + a²) + 4
Plug a = 5
b = -3
= 13(5×(-3) + 5a²) + 4
= 13(-15 + 5(25)) + 4
= 13(-15 + 125) + 4
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
= 13(110) + 4
= 1430 + 4
= 1434
Thus, the value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.

Ok
the sets are
natural numbers (or counting numbers), this is like 1,2,3,4,5 etc
whole numbers, this is including 0, so 0,1,2,3,4,5,6 etc
integers, this includes the previoius set and negatives, so -3,-2,-1,0,1,2,3,4,5 etc
rational numbers, this is the set of numbers that can be written in form a/b where b≠0, so all integers can be written like this, like example -3=-3/1, so -7/9 belongs here
-7/9 goes in the rational set
