Question and answer
Q: The distance between two cities is ninety miles, and a woman drives from one city to the other at a rate of 45 mph. At what rate must she return if the total travel time is three hours and forty
minutes? 27 mph 45 mph 54 mph
A: 1st leg DATA: distance = 90 mi ; rate = 45 mph ; time = d/r = 2 hrs. - - 2nd leg DATA: distance = 90 mi ; time = [3 2/3 - 2] = 1 2/3 hrs; rate = 90/(5/3) = 54 mph - - - - Ans: 54 mph ====================== Cheers, Stan H.

What is the area of the original rectangle? 12 square inches 48 square inches 96 square inches Weegy: The width and the length of a rectangle are consecutive even integers. If the width is decreased by 3 inches, then the area of the resulting rectangle is 24 square inches. What is the area of the original rectangle? B. [ 48 square inches ] User: Which of the following constants can be added to x2 - 10x to form a perfect square trinomial? 10 25 100 Weegy: The answer is 1/4. Here, I'll show you how to get that answer: Trial and Error Method: 1) 1/4, [ 1/2 and 1 are the possible answers in the choices but we know that 1/2 is not a perfect square so it's not possible for 1/2 to be the answer. 2) Now try 1/4 and 1 and add them to the equation to get: x2 - x + 1/4 x2 - x + 1 3)Use the perfect square formula if you can: x2 - x + 1/4 becomes (x-1/2)2? Yes! x2 - x + 1 becomes (x-1)2 ...No! that's wrong because (a-b)2 = a2-2ab +b2 Thus, 1/4 is the answer. Easy Formula Method: 1) In a perfect square trinomial, c = (b/2a)2. a=1 because it's the co-efficient of x2 b=1 because it's the ... (More)

(x - 2)(x - 3) = 2
x^2 - 3x - 2x + 6 = 2
x^2 - 5x + 4 = 0
(x - 1)(x - 4) = 0
x = 1 or x = 4
The solution set of (x - 2)(x - 3) = 2 is {1, 4}

2x(x - 1) = 3
2x^2 - 2x - 3 = 0
a = 2, b = -2, c = -3
b^2 - 4ac = (-2)^2 - 4(2)(-3) = 4 + 24 = 28
x = (2 ± sqrt 28)/4
= (2 ± 2 sqrt 7)/4
= (1 ± sqrt 7)/2

y(y + 4)(y - 6) = 0 is a quadratic equation. FALSE.
y(y + 4)(y - 6) = 0
y(y^2 - 2y - 24) = 0
y^3 - 2y^3 - 24y = 0 which is not a quadratic equation.
