What is wrong with the following equation?x2+x−20/x−4=x+5a. (x−4)(x−5)≠x2+x−20b. The left-hand side is not defined f
or x = 0, but the right-hand side is.c. The left-hand side is not defined for x = 4, but the right-hand side is.d. None of these - the equation is correctIn view of part (a), explain why the equation lim x rightarrow 3 x2+x-12/x-3= lim x rightarrow 3 (x+4) is correct. 1. Since x2+x-12/x-3 and x + 4 are both continuous, the equation follows. 2. Since the equation holds for all x 3, it follows that both sides of the equation approach the same limit as x Rightarrow 3. This equation follows from the fact that the equation in part (a) is correct. 4. None of these 5. the equation is not correct.
A) 2L + 2W = 48 B) L * W = 140 B) W = 140 / L Inputting this to equation A) A) 2L + 2*(140 /L) = 48 L + 140/L = 24 Multiplying both sides by "L" L² + 140 = 24L L² -24L +140 = 0 (L -10) * (L-14) = 0 L= 10 L = 14 If length = 10 then width =14 If length = 14 then width = 10
