Answer:
Option A. 
Step-by-step explanation:
Let
y -----> the height of fudge brownies in centimeters
x ----> teaspoons of baking powder
step 1
Find the slope
The formula to calculate the slope between two points is equal to
take the points
(5,2.15) and (6,2.43)
substitute the values
step 2
Find the equation of the line in point slope form

we have

substitute

Isolate the variable y



350 because 25x10 is 250 and 20x5 is 100 so you add them and get 350
Answer: A
Step-by-step explanation:
Use pythagorean thm to solve for the hypotenuse. so
is 13.4
Given dimensions of a rectangular garden are:
length = 2(x+6) feet
width = 3.5x feet
using the distributive property on length we get, length = 2x+12
Perimeter of a rectangle is 2(length+width)
So, P = 2(2x+12+3.5x)
Solving it we get,
P = 2(5.5x +12) ..............adding like terms
P =
.............multiplying and adding
P = 11x+24
So, perimeter is 11x+24 feet. This value of fencing will be needed.
