Step-by-step explanation:
<u>Step 1: Define Systems</u>
-4x = y - 42
x = 18 + y
<u>Step 2: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: -4(18 + y) = y - 42
- Distribute -4: -72 - 4y = y - 42
- [Addition Property of Equality] Add 4y on both sides: -72 = 5y - 42
- [Addition Property of Equality] Add 42 on both sides: -30 = 5y
- [Division Property of Equality] Divide 5 on both sides: -6 = y
- Rewrite/Rearrange: y = -6
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x = 18 + y
- Substitute in <em>y</em>: x = 18 - 6
- Subtract: x = 12
The height of an airplane as it descends to an airport runway is a quantity which has a unit that is usually rounded to a certain terminating degree of accuracy (i.e. 1, 2, ..., n decimal places)
Thus the set of rational<span> numbers best describes the height of an airplane as it descends to an airport runway.
A rational number is a number which can be represented in the form a/b where a and b are integers. It is usually identified by a terminating or a recurring decimal number.

Answer:
(4+x)^2
Step-by-step explanation:
Rewrite 16 as 4^2
4^2+8x+x^2
Check the middle term by multiplying 2ab and compare the result with the middle term in the original expression.
2ab=(2)x(4)x(x)
Factor using the perfect square trinomial rule a^2+2ab+b^2=(a+b)^2, where a=4 and b=x
Anwser:
(4+x)^2
Hopefully that is the correct anwser you're looking for!
