1.50c + 4.00a = 5,050
c + a = 2,200
-1.50 (c + a = 2,200)
1.50c + 4.00a = 5,050
-1.50c - 1.50a = -3,300
2.5a = 1750
a = 700
c + 700 = 2,200
c = 1500
700 adults and 1500 children attended the fair.
Answer:
- Circle X with radius 2 cm.
- Either of two lines parallel to AB.
Step-by-step explanation:
1. The definition of a circle is all the points in a plane that are at some radius r from a given point (the circle center). That is what you have, with a radius of 2 cm.
__
2. Parallel lines are the same distance apart everywhere. Each line will have two parallel lines at some given distance from it, one on each side. Here, the separation distance from AB is 1 cm, so your locus of points is the two lines parallel AB that are 1 cm from it on either side.
Option C: (x+4) and (x-1) are the factors of the equation
Explanation:
Given that the equation is 
We need to determine the factors of the equation.
Splitting the middle term, we get,

Grouping the terms, we have,

Let us factor out the term (x+4), we have,

Thus, the factors of the equation are (x+4) and (x-1)
Hence, Option C is the correct answer.
Memorize the side ratios of a 45-45-90 right triangle.
The ratio between the sides of this triangle is 1:1:Sqrt(2), which means that the length of the legs are equal, and the length of the hypotenuse is simply the leg length multiplied by the square root of two.
