Answer:
Complete the square on x by adding <u>49</u> to both sides.
Complete the square on y by adding <u>81</u> to both sides.
Step-by-step explanation:
We have been given an equation . We are asked to complete the squares for both x and y.
We know to complete a square, we add the half the square of coefficient of x or y term.
Upon looking at our given equation, we can see that coefficient of x is 14 and coefficient of y is 18.
Now, we will add 49 to complete the x term square and 81 to complete y term square on both sides of our given equation as:
Applying the perfect square formula , we will get:
Therefore, We can complete the square on x by adding <u>49</u> to both sides and the square on y by adding <u>81</u> to both sides.
Answer:
<em>The fraction of the beads that are red is</em>
Step-by-step explanation:
<u>Algebraic Expressions</u>
A bag contains red (r), yellow (y), and blue (b) beads. We are given the following ratios:
r:y = 2:3
y:b = 5:4
We are required to find r:s, where s is the total of beads in the bag, or
s = r + y + b
Thus, we need to calculate:
Knowing that:
Multiplying the equations above:
Simplifying:
Dividing [1] by r:
Substituting from [2] and [3]:
Operating:
The fraction of the beads that are red is

Answer:
460 USD
Step-by-step explanation:
monthly earnings = 250 x 4 = 1000
