Question

if the average of 7,12,6,10 and p is 8 find the value of p​

Answer 1

Step-by-step explanation:

For an expression of the form (a + b)(c + d), the expanded version is ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second. Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3)(x - 1).
