10x^2-6x^2 = 4x^2
-64-36 = 100
4x^2 -100 = 0
(2x -10)(2x+10)
X = 2/10 and x = - 2/10
Answer:
could u put this in english
5x+40 factors to 5(x+8). Notice how distributing the 5 back through to each term in the parenthesis gives
5 times x = 5x
5 times 8 = 40
So 5*(x+8) = 5*x+5*8 = 5x+40
Therefore, the factors are 5 and (x+8).
The dimensions of the sandbox are 5 feet by (x+8) feet.
We don't know the numeric value of (x+8) since we don't know the value of x, so we leave it as is.
Let b and p represent the distances traveled by baby and pickles, respectively.
.. b +p = 27
.. p = 5(3b -1)
Substituting, you have
.. b +5(3b -1) - 27
.. 16b -5 = 27
.. 16 b = 32
.. b = 2
The baby travel was 2 miles.
The pickles travel was 25 miles.
