What are two numbers that when you subtract them who get 13 and when you x them you get 30?
The pair of numbers are 15 and 2, or -2 and -15 15 - 2 = 13 15 x 2 = 30 -2 - (-15) = -2 + 15 = 13 (-2)(-15) = 30
What is x2 plus 15x equals 30?
It's an equation. If you want to solve it for x, you can do so as follows: x2 + 15x = 30 x2 + 15x + (15/2)2 = 30 + (15/2)2 (x + 15/2)2 = 30 + 225/2 x + 15/2 = ± √(285/2) x = (-15 ± √570) / 2
What is the answer to X squared - x?
x^2-15x+14=0 Delta = (-15)^2-4*1*14 = 169 = 13^2 so x=(15-13)/2=1 or x=(15+13)/2=14
What two thirds of 15?
2/3 x X = 15 2/3 x X = 15/1 Step(s): Left out on purpose in case this is your homework... (you can get it from here) X = 10
What is 2 times -15?
2 x 1.5 = 3three2 x 1.5 = 3
What is the answer to -7x 3-15divided into2?
-7x3-15 _______=x 2 -15-15 _______=x 2 -30 _______=x 2 -15=x
How do you know what 12 times 15?
12 x 15 = 180 (10 x 15) + (2 x 15) = 180 15 x 2 x 6 = 180
What is the maximum area of a triangle having 15 cm as the sum of its base and height?
Let b = x, so h = 15 - x. A = (bh)/2 A(x) = [x(15 - x)]/2 A(x) = -(1/2)x2 + (15/2)x since the coefficient of x2 is negative, we have a maximum value of the area when x = (-15/2)/[2(-1/2) = 15/2 A(15/2) = -(1/2)(15/2)2 + (15/2)(15/2)] = -225/8 + 225/4 = (-225 + 500)/8 = 225/8 Thus, the maximum area of the given triangle would be 225/8 cm2.
