Originally we have
length = x
width = x-2
since the width is 2 inches smaller than the length
now let's triple each dimension. Multiply the expressions by 3 to get
new length = 3*x
new width = 3*(x-2) = 3x-6
Now onto the area
area = (length)*(width)
area = (3x)*(3x-6)
area = 3x*3x-3x*6
area = 9x^2 - 18x
So the new larger rectangle has area of 9x^2-18x
Answer:
16
Step-by-step explanation:
dot product = x1x2 + y1y2
= (-5)(-8 + (4)(-6)
= 40 - 24
= 16
If you start with the tens it will mess up the problem
Can't really factor this:
27 + 12 = 39

Answer:
The distance between the pair of points is 12.0 (to the nearest tenth)
Step-by-step explanation:
The distance between a pair of points in a coordinate system is found by the formula:
d =
where, the points are:
From the graph,
Substitute the points into the formula:
