Okay the two legs ( as I like to call it ) or the absolute value symbols mean anything inside of it is automatically positive :)
so | 1 + ( -15 ) | = | -14 |
But with the absolute value symbols makes the negative 14 into positive
Now you are left with 8 + 14
22
C is 6 because the absolute value of -19 -13 would be 19-13 which equals 6
Answer:
r ≅ 10.2m
Step-by-step explanation:
Use formula: s = r * θ
s = arc length
r = radius
θ = angle in radians
8 = r * π/4
r = 32/π
r ≅ 10.2m
Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of 16x2 – 40x + 25 square inches. What is the side length, in inches, of the pet shop sign?
Answer:
the length of the sign is inches
Step-by-step explanation:
Given
Area of the square of design =
First we find the roots of equation
The roots of the quadratic equation are given by
where
That is, the factors of the polynomial are and .
So, Area of the square design = =
Area of a square = Length^2
Thus, the length of the sign is inches
