A=LW(1/2)
is the standard formula, so plug in for variables
A=(30)(12)(1/2)
You simplify and get
A=180 in
So the complete answer is
-The area of the bandana is 180inches.
I think it’s add or subtract terms away from variable
Slope = (-1+7)/(-4-2) = 6/-6=-1
answer
-1
Answer:
(9 x - 7 y) (9 x + 7 y)
Step-by-step explanation:
Factor the following:
81 x^2 - 49 y^2
Hint: | Express 81 x^2 - 49 y^2 as a difference of squares.
81 x^2 - 49 y^2 = (9 x)^2 - (7 y)^2:
(9 x)^2 - (7 y)^2
Hint: | Factor the difference of two squares.
Factor the difference of two squares. (9 x)^2 - (7 y)^2 = (9 x - 7 y) (9 x + 7 y):
Answer: (9 x - 7 y) (9 x + 7 y)
( x - 8 )² = 144 / √ (take the square root of both sides of equation )
x - 8 = 12
x = 20 feet
Answer: D) 20 feet by 20 feet
