Process:Square the number at the end of each of the numbers and add them together. The ending of that number will match the sum of the two squared numbers together.A: 44²+77²=4477 4²=16 7²=49 16+49=65B: 55²+66²=5566 5²=25 6²=36 25+36=61C: 66²+55²=6655 6²=36 5²=25 36+25=61D: 88²+33²=8833 8²=64 3²=9 64+9=73E: 99²+22²=9922 9²=81 2²=4 81+4=85Solution:D is the only equation that matches the rule: therefore the equation is correct.Question 3Aim: To work out an algebraic expression and add the sum of the variables together.Process:Solution:0.5+4+6=10.5Question 4Aim: To find out the area of a rectangle with an unknown length.Process:Solution: 15x18=270
