Question

Given that k=cd2 + e find the value of c when k=3 ,d=2 and e=5

Answer 1

Answer:

-1/2

Step-by-step explanation:

k= cd2 + e

now putting the values

3 = c × 2 × 2 + 5

3 = 4c + 5

4c = -2

c = -1/2

Answer 2

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

           Given data:- $k=3,d=2,e=5.$

           To find:- Value of above expression $k=cd2+e.$

           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 value k,d, and e in the given equation we get,

             $k=cd2+e\\=>3=c\times2\times2+5\\=>3=4c+5\\=>4c=3-5\\=>4c=-2\\=>c=\frac{-2}{4}\\=>c= -\frac{1}{2}$

      Hence we will get $c=-\frac{1}{2}.$
