|x| = 5
x = 5 or x = -5
You need a graph that has a closed dot on -5 and a closed dot on 5.
Answer: B. Picture B
Answer:
(1,-3)
Step-by-step explanation:
The reason why it would be (1,-3) is because (1,3) is in the first quadrant which is (+,+) and when it is reflected across the x axis, it is then placed into the fourth quadrant which is (+,-). So you need to make the 3 negative and then it will be reflecting across the x axis
STEP 1:
find the length of the sides of the square
AREA FORMULA (for a square)
x= side
A=x^2
225=x^2
take square root of both sides
15 feet= x
STEP 2:
find perimeter
PERIMETER FORMULA (for a square)
x= side of square
P= 4x
use x value from step 1
P= 4(15 ft)
P= 60 feet
ANSWER: The perimeter is 60 feet.
Hope this helps! :)
