12x2 - 28x - 15= 12x2 - 18x - 10x - 15= 6x(2x - 3) - 5(2x - 3)= (6x - 5)(2x - 3)
is 28x squared? if it is, the answer would be, 3(2x+5)(4x+3).
Factored, that's (x - 6)(5x + 2) x = 6, -2/5
The lateral area L.A. of the right triangular prism is the sum of the areas of its lateral faces, which are rectangles with length the height (l = h = 15) and wide the sides of the triangle (w1 = leg1 = 3, w2 = leg2 = 5, w3 = hypotenuse = 7). So we have: L.A. = (15 x 3) + (15 x 5) + (15 x 7) L.A. = 15(3 + 5 + 7) L.A. = 225 Thus, we can also say that the lateral area of a prism is the product of the perimeter of its base with the height of the prism.
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).

x=1/3,3/5
The expression -28x+35 is equivalent to 7y(-4x+5)
is 28x squared? if it is, the answer would be, 3(2x+5)(4x+3).

The probability that you pick 3 white balls is 0.05 or 5%.----------------------------------------------------------------------------------------------------EXPLANATIONThe probability of first drawing a white ball is: P(W1) =3/6.The probability of drawing a white ball given the event that you already draw awhite ball in the first draw and not replacing it back is: P(W2│W1) =2/5.The probability of drawing a white ball on the third draw given the event that awhite ball was drawn in the first and in the second draw is: P(W3│(W1UW2)) =1/4Now, the probability of drawing 3 white balls one by one with out replacement(taking all 3 balls at a time gets the same analysis and result) is:P(W1UW2UW3) =P(W1)∙P(W2│W1)∙P(W3│(W1UW2)) =(3/6)∙(2/5)∙(1/4) =1/20=0.05 =5%.
It depends on what the statement means. If the total fish caught in the first part of the statement is 5 fish each for a total of 25 fish, it will take them 1 minute. If the total is 5 fish, it took each fisherman 5 minutes to catch one fish, it will take them 5 minutes.

There is no specific rule. Among the infinitely many possibilities are y = 5 (whatever x is) y = x + 4 y = 27x - 22 y = x2 + 4x y = 28x/4 - 2
