Answer:
2 * ( [2w-8] + w)
Step-by-step explanation:
width = w
Length = 2w -8
Perimeter of Rectangle = 2 (l+b)
= 2 * ( [2w-8] + w)
Answer:
Step-by-step explanation:
given the expresseon that relates the number of ounces y and number of pounds x as y = 16x
The equation is a directly proportionality with a Proportionality constant of 16.
Thus means that the value of y keeps increasing by a factor of 16 for any value of x.
The ordered pairs that represent the number of pounds and the number of ounces are;
If x = 3
y = 16(3) = 48
Hence (3, 16) is an ordered pair
also if x = 10
y = 16(10) = 160
Therefore (10, 160) is another ordered pair
Hence the correct ordered pairs are (3, 16) and (10, 160)
You may be able to use the 30, 60, 90 rule, but if not, it is a semicircle so you may be able to base your answer off that.
Answer:
k=3
Step-by-step explanation:
The given system of equations are
We need to find the value of k if the given system of equation have infinite number of solutions.
If two equations and have infinite number of solutions, then
Using this we get
Therefore, the value of k is 3.
