The distributive property of division over addition and substraction is idk
Answer:
The change in the area of the rectangle is 0 square feet
Step-by-step explanation:
To solve this problem we have to calculate the area of the two rectangles that give us
first we have to know the formula to calculate the area of a rectangle
a = area
l = length = 12ft
w = width = 5ft
a = l * w
we replace the known walues
a = 12ft * 5ft
a = 60ft²
we do the same with the other rectangle, but first we have to calculate its sides
w = 5ft - (5ft * 20/100)
w = 5ft - 1ft
w = 4ft
l = 12ft + (12ft * 25/100)
l = 12ft + 3ft
l = 15ft
a2 = 15ft * 4ft
a2 = 60ft²
to calculate the change in the area we subtract (a - a2)
a - a2 =
60ft² - 60ft² = 0ft²
Answer:
a is 3,2 b is 1,-2 and c is -2,1
Step-by-step explanation:
u take the first number then you just put em together
Answer:
Step-by-step explanation:
step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to
we have the points
(2,24) and (6,16)
substitute in the formula
step 2
Find the equation of the line in slope intercept form
we have
----> the k-intercept is the point (0,28) see the graph
substitute
Large would be 1495
Medium would be 997
Small would be 498
Look a the work I did, it has an equation in it. The equation I got is 3x+2x+x=2940
