Answer:
the sqare root of 19.9 is 4.46094160464
A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A
B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches
Answer:
Whole numbers are also integers. There are other integers which are the opposites of the whole numbers (−1, −2, −3, ...). These negative numbers lie to the left of 0 on the number line. Integers are the whole numbers and their opposites.
Answer:
x = 3
Step-by-step explanation:
The fractions need to have common denominators. So, we would make the common denominator (x + 3)(x - 3), or, x^2 - 9
Multiply the numerator by the same number or variable as the denominator and then combine.
Once their is x and a number left you would solve for x.
Use the binomial theorem:

The <em>x</em> ³ terms occurs for 5 - <em>k</em> = 3, or <em>k</em> = 2, and its coefficient would be
