The rate of increase is found by differentiating with resepect to time. The product rule comes into play here.
A = LW
dA/dt ≈ (dL/dt)·W + L·(dW/dt)
... = (6 cm/s)·(5 cm) + (7 cm)·(3 cm/s)
... = 30 cm²/s + 21 cm²/s
... = 51 cm²/s . . . . rate of area increase
165 because when u do 11x15 u get 165 which is length times width and that’s how u get the area. The area is 165
For the first question on the screenshot, you need to put this same exact order as I put it.
A D B C
Now the second question
A = 3 units
B = 4 units
C = 4 units
D = 3 units
(16+4) * x (or any letter for the variable)
Answer:
Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.
