Question 9
6. (a) 13c + 7d final answer (b) 20ab final answer
Worked Solution & Example Answer:6. (a) 13c + 7d final answer (b) 20ab final answer - OCR - GCSE Maths - Question 9 - 2017 - Paper 2
Step 1
(a) 13c + 7d final answer
Answer
To solve for the expression 13c + 7d, we first need to recognize the coefficients and the variables involved.
-
Identify the coefficients of each term:
- The coefficient of c is 13.
- The coefficient of d is 7.
-
Combine the terms where applicable. Since this expression already signifies a linear combination of the variables c and d, the final answer remains:
Step 2
(b) 20ab final answer
Answer
To find the product of the variables 'a' and 'b' with the coefficient 20, follow these steps:
-
Start with the expression, which is given as '20ab'.
-
Recognize that the expression is already simplified and represents the multiplication of the coefficient 20 with the terms a and b.
-
Therefore, the final answer for this expression is:
