work out the value of y when a = 8.5 and b = 1.5, given that y=(a+b)(a-b)
Question
work out the value of y when a = 8.5 and b = 1.5, given that y=(a+b)(a-b)
Solution
Sure, let's solve the equation step by step.
Step 1: Substitute the values of a and b into the equation. So, y = (8.5 + 1.5)(8.5 - 1.5)
Step 2: Simplify the equation. So, y = (10)(7)
Step 3: Multiply the numbers. So, y = 70
Therefore, the value of y is 70 when a = 8.5 and b = 1.5.
