Answer:

(x-7)(x+4)

Step-by-step explanation:

To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to -28 and add to -3 for a and b.

28: 1,2,4,7,14,28

-7+4 = -3

x^2-3x-28 = (x-7)(x+4)

One side of a rectangle is 10 feet shorter than twice another side. Find the length of the shorter side if we also know the peri
seropon [69]

Answer:

  6 feet

Step-by-step explanation:

Let x represent the length of "another side." Then "one side" is ...

  2x -10 . . . . . . 10 feet shorter than twice another side

The sum of these two side lengths is half the perimeter, so is ...

  x + (2x -10) = 14 . . . . . two sides are half the perimeter

  3x = 24 . . . . . . . . . . . . add 10, collect terms

  x = 8 . . . . . . . . . . . . . . .divide by the coefficient of x

  (2x -10) = 2·8 -10 = 6 . . . . find "one side"

We have found "one side" to be 6 feet long, and "another side" to be 8 feet long. The shorter side is 6 feet.

Multiply or divide the following measurements. Be sure each answer you enter contains the correct number of significant digits.
nydimaria [60]

Answer:

93.4 g/mL x 20. mL = 1868g.

489.7m / 53.061 s = 9.23 m/s

216.3 m/66.4 s = 3.26 m/s.

Step-by-step explanation:

Let's analyze each case.

93.4 g/mL x 20. mL

Hewe we are multiplying g/ml*ml. So we have the answer is (g*ml/ml) = g.

So

93.4 g/mL x 20. mL = 1868g.

489.7m / 53.061 s

We are dividing a measurement in m by a measurement in s. So the answer is in m/s.

So

489.7m / 53.061 s = 9.23 m/s

216.3 m/66.4 s

Same as above.

We are dividing a measurement in m by a measurement in s. So the answer is in m/s.

So

216.3 m/66.4 s = 3.26 m/s.
