Question

p = 4 , q = -2 , r = 4

(b) 2p - q + 3r​

Answer 1

Answer:

Correct answer is 18

Step-by-step explanation:

p=4, q=-2, r=4

2p-q+3r

2×4-2+3×4

8-2+12

6+12

18

Answer 2

Answer:

We will get the value is 22.

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

        Given data:- $p=4,q=-2,r=4.$

        To find:- $2p-q+3r.$

        Solution:-

• To solve the above equation we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

     Now put the values p,q, and r in the given equation we get,

     $2p-q+3r\\=2(4)-(-2)+3(4)\\=8+2+12\\=22$
