Answer: it depends on the rectangle.
Step-by-step explanation: “The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.”
Answer:40% weight increase
Step-by-step explanation:
step 1
find the equation of the line
where
x-------> numbers of light bulbs
y-------> the total cost in $
let
A (0,0) B (10,18)
slope m=18/10-----> m=1.8
step 2
with m=1.8 and the point A (0,0)
y-y1=m*(x-x1)------> y=1.8x
step 3
for x=1
y=1.8*1------> y=$1.8
therefore
the answer is
the cost of a single light bulb is $1.8
Answer:
27
Step-by-step explanation:
The expression is 3 + 4z
First, you must know what the value of the variable "z" is.
Because the problem already tells you that z = 6, all you have to do is substitute z with 4:
3 + 4z = 3 + 4(6)
Next, solve using the Order of Operations (P.E.M.D.A.S.).
According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:
3 + 4(6) = 3 + 24 = <u>27</u>
(2,-1) is the answer hope this helps
