The answer is 68/5 - 54/5i
Answer:
the triangle formed from the coords is 3cm by 9cm so try 3 × 9 = 27 then 27 ÷ 2 = 13.5 from the formula a = ½bh?
Step-by-step explanation:
You do the same as with number you take out the largest allowed amount. For example for 8 you could take out x^2 and y^2 along with the normal factors, So once you factor everything out you would be left with 27x^2y^2(y^3-3x)
69.) 4(x + 5) = 4(x) + 4(5) = 4x + 20
70.) 4(2b - 5) = 4(2b) - 4(5) = 8b - 20
71.) Area = length x width = 11(3x + 2) = 33x + 22
5(5 + 2y) = 25 + 10y
