It’s easiest to think about it this way:
If the pond is 15 feet wide, then adding 3 feet to each side would increase the side length to the square by six feet (3 feet on each side). This makes the area within the square equal to 18x18 feet, or 324 square feet. But, this isn’t the area of the sidewalk, it’s the area of the sidewalk plus the area of the pool.
The pool is fifteen feet wide, which means that it has an area of 225 square feet. So, to find the area of the side walk, we can subtract the area of the pool from the area of the pool and sidewalk, which will give us the area of the sidewalk by itself.
324-225=99 square feet.
The pool has an area of 225 square feet, and the sidewalk has an area of 99 feet.
Answer:
-3
3/2
Step-by-step explanation:
Y intercep is the point where the line intercepts the y axis. That is 3 in this graph.
slope. Choose two points. For the sake of explainin, I am choosing
(-3,1)
and (0,3). That’s the y intercept!!
The slope is the rate of increase. We have to measure it like we do with stairs. The rise divided by the run
the rise is 2. See the picture. The run is 3(change in x) the x increases by 3 between 2 integer points while the y changes by 3(change in y —>3 minus 1)
Rise= 3
run =2
Slope=rise/run=3/2
Answer:
x=3
Step-by-step explanation:
Simplifying
9x + -4 = 3x + 14
Reorder the terms:
-4 + 9x = 3x + 14
Reorder the terms:
-4 + 9x = 14 + 3x
Solving
-4 + 9x = 14 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-4 + 9x + -3x = 14 + 3x + -3x
Combine like terms: 9x + -3x = 6x
-4 + 6x = 14 + 3x + -3x
Combine like terms: 3x + -3x = 0
-4 + 6x = 14 + 0
-4 + 6x = 14
Add '4' to each side of the equation.
-4 + 4 + 6x = 14 + 4
Combine like terms: -4 + 4 = 0
0 + 6x = 14 + 4
6x = 14 + 4
Combine like terms: 14 + 4 = 18
6x = 18
Divide each side by '6'.
x = 3
Simplifying
x = 3
