Answer:
x > 2
Step-by-step explanation:
Given
4x + 
(2x + 4) > 12 ← distribute and simplify left side
4x + x + 2 > 12
5x + 2 > 12 ( subtract 2 from both sides )
5x > 10 ( divide both sides by 5 )
x > 2
<u>Given:</u>
The circle has a diameter of 30 cm and a chord of 10 cm is drawn.
Radius of the circle = 15 cm
Half of the chord = 5 cm
We need to determine the distance of chord from the center of the circle.
<u>Distance of chord from the center of the circle:</u>
Let us use the Pythagorean theorem, to find the distance between the center and the chord.
Let d denote the distance between the center and the chord of the circle.
Thus, we get;
Taking square root on both sides, we get;
Thus, the distance between the center and the chord of the circle is 14.14 cm.
Hence, Option A is the correct answer.
Answer:An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ... ℤ is a subset of the set of all rational numbers ℚ, which in turn is a subset of the real numbers ℝ.

Answer:
A. 191.54 ft²
B. $2011.17
Step-by-step explanation:
Part A involves multiplying to find the area of the living room using the formula to find the area of a rectangle.
A = b*h (original formula)
A = 15.7*12.2 (substitute values)
A = 191.54 (multiply)
The area of his living room is 191.54 ft²
Next, you need to multiply the number of ft² by the cost per ft² to find the cost to tile the living room
Cost = $10.50*191.54 (equation)
Cost = $2011.17 (multiply)
The total cost of tiling the living room would be $2011.17
