Answer:
x = 0
Step-by-step explanation:
= 2 - x ( square both sides to clear the radical )
x + 4 = (2 - x)² ← expand using FOIL
x + 4 = 4 - 4x + x² ( subtract x + 4 from both sides )
0 = x² - 5x ← factor out x from each term
0 = x(x - 5)
equate each factor to zero and solve for x
x = 0
x - 5 = 0 ⇒ x = 5
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = 0
left side = = = 2
right side = 2 - 0 = 2
then x = 0 is a solution
x = 5
left side = = = 3
right side = 2 - 5 = - 3 ≠ 3
then x = 5 is an extraneous solution
The consult must make at least 600 dollars. That means the combination of reviews and new written pieces must be at least $600, or greater than or equal to (<span>≥) $600.
You are also told that each new piece = $120 and each review = $60. Let's use variables n = new piece and r = review. (You might be given different variables for your answer choices). That means the total money made from a combination of new pieces and reviews is:
120n (money made from each new piece times n number of new pieces) + 60r (money made from each review times r number of reviews).
Put that all together to get your inequality:
120n + 60r </span>≥ 600
-----
Answer: 120n + 60r ≥ 600
The answer is 4 for both x and y
6 • 4 = 24
12 • 4 = 48
24 - 48 + 24 = 0
-24 + 24 = 0
-24 - (-24) = 0
Answer:
Step-by-step explanation:
Since it is a square and we know the hypotenuse squared is equal to the sum of its squared sides
d^2=2s^2, we are told d=80 so
2s^2=80^2
s^2=3200
s=3200^(1/2)
P=4s
P=4(3200^(1/2))
P=160(2^(1/2) yds or approximately
P=226.27 yds
