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.

The triangle STU shown on the coordinate grid below is reflected once to map onto triangle S'T'U': Triangle STU drawn on a 4 qua
Andreyy89
Given that triangle <span>STU is reflected once to map onto triangle S'T'U'.
Given that triangle STU has vertices S(8, 6), T(2, 2), U(5, 1).

If vertex T' is at (2, −2), this means that triangle STU is refrected across the x-axis.

A refrection across the x-axis results in an image that has the same x-value as the pre-image but a y-value that has the opposite sign of the y-value of the pre image.

Thus, a point, say (x, y), refrected over the x-axis will result in an image with coordinate (x, -y)

Therefore, given that the coordinate of S is (8, 6), then the coordinates of vertex S'</span>  is (8, -6).

Use the grouping method to factor the polynomial below completely.
xxMikexx [17]
The correct answer is C, if you use the distributive property and multiply all of them by each other you would get x^3+2x^2+3x+6.

Hope this helps :-)
