If the question is:
"<span>Find two positive numbers whose difference is 28 and whose product is 3900</span>"
If the larger number is x, then
x-3900/x=28
multiply by x and transpose
x^2-28x-3900=0
Factor
(x+78)(x-50)=0
Using the zero product property,
x=-78 or x=50, ie. x=50, y=-78
NOTE: if question requires both numbers be positive, there is no solution.
Answer:
X^2 -5x -36
Step-by-step explanation:
formula of an area of a rectangle: ab
a-length
b-width
(x+4)*(x-9) = x^2 -5x -36
Answer:
Step-by-step explanation:
(3, 0) (0, 2)
(2-0)/(0-3) = 2/-3= -2/3
y - 0 = -2/3(x - 3)
y = -2/3x + 2
(3x(a)-6x)- (6a-12) Multiply the outside with the inside
