<span>Let the length of one side of the rectangle be x.
Then the opposite side of the rectangle also has a length of x.
The sum of the other two sides must be 17 - 2x.
So the length of one of these sides is 8.5 - x.
The length of two sides of the rectangle are x and 8.5 - x.
To find the area, we need to multiply these two values.
A(x) = (x) (8.5 - x) = 8.5x - x^2</span>
Answer:
47,04 miles
Step-by-step explanation:
you can clearly see something 20 feet away that you should be able to see from that distance. If a person can see 6 miles from a height of 25 feet, by dividing 196 by 25 we can get the following calculation
196 ÷ 25 = 7,84
Then you gan multiply
7,84 × 6 = 47,04 miles
Or equal to 75703,542 meters
Answer:
y = 3x + 19
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 8 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes , thus
y = 3x + c ← is the partial equation
To find c substitute (- 4, 7) into the partial equation
7 = - 12 + c ⇒ c = 7 + 12 = 19
y = 3x + 19 ← equation of parallel line
