(4c - 3d)(3c + d) =
= 12c² + 4cd - 9cd - 3d² =
= <u>12c² - 5cd - 3d²</u>
Answer:

2y^3 / x^2 - y^2
hope this helps and is right. p.s i really need brainliest :)
if my answer is wrong then I am incredibly sorry!
120/4 = 30
120 x 2 = 240
240 + 30 = 270
270 grams of flour were used
Since that is a triangle the expression would be b x h / 2. So 12*12 = 144 / 2 = 72. The answer is 72.
