The formula for the area of a rectangle is length times width, or A=l·w
The Area A=256
The width is w
The lenght is given as 6 feet less than 4 times its width, or in math language this is l=4w-6
Let's go back to the formula
A=l·w ⇒ 256=(4w-6)·w
simplify ⇒ 256=4w²-6w
put everything on the same side and set the equation equal to zero
⇒ 4w²-6w-256=0
Solve for w using quadratic formula
You are going to get two answers after using the quadratic formula: one positive and one negative. Just remember it doesn't make sense to get a negative answer if we are talking about width, so use the positive answer only
w≈8.7851 units
the ratio that is equal to 10:85 is 20:170 because if you multiply both sides by two you get 20:170
Answer:
35
Step-by-step explanation:
0.25 x 140 = 35
We have to translate the point P ( - 8, 6 ) to P ` ( - 10, 2 ).
- 10 = - 8 - 2
2 = 6 - 4
The translation rule is:
( x `, y ` ) = ( x - 2 , y - 4 )
