Answer:
A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers. We have a top number, the numerator, and a bottom number, the denominator. For example, 1/2 is a fraction.

See answers below.
Step-by-step explanation:
<u>Large Rectangle:</u><u> </u> length x width = (x + 3)(x - 4) =
x² - 4x + 3x - 12
x² - x - 12
<u>Smaller Rectangle:</u> length x width = (x)(3) = 3x
<u>Shaded Region: </u>shaded area = lg. rectangle minus small rectangle
A = (x² - x - 12) - 3x
A = x² - 4x - 12
<u>Solve for x, if shaded reion's area is 48 square units: </u>
48 = x² - 4x - 12
x² - 4x - 12 -48 = 0
x² - 4x - 60 = 0
(x - 10)(x + 6) = 0
x - 10 = 0 or x + 6 = 0
x = 10 or x = -6
But x represents a length, so x cannot be -6.
x = 10

Answer: x = 29</h3>
========================================================
Work Shown:
A = 2x+3
B = x
angles A and B are complementary, so they add to 90 degrees
A+B = 90
(2x+3)+(x) = 90
2x+3+x = 90
2x+x+3 = 90
3x+3 = 90
3x+3-3 = 90-3
3x = 87
3x/3 = 87/3
x = 29
Extra info:
2x+3 = 2(29)+3 = 58+3 = 61
Note that 29 and 61 add to 29+61 = 90
