The perimeter is just the sum of all its sides, in this case, 14+8+14+8 is the perimeter of that one.
now, it gets enlarged with a scale factor of 10, namely it gets blown up 10 times, so the length and the width get blown up that much, thus 10*8 and 10*14.
the new perimeter is then (10*8) + (10*14)+(10*8) + (10*14).
Answer:
The y-intercept is 1/3.
Step-by-step explanation:
The equation given is in slope-intercept form. Recall that in slope-intercept form:
<em>m </em>is the slope while <em>b</em> is the y-intercept.
Therefore, -2/9 would be the slope while 1/3 would be the y-intercept.
Let X be the width of the path.
The width of the path would be the width of the pool plus 2x, so 2x +16
The length of the path would be the length of the pool plus 2x, so 2x+22
The total area is 832 square feet.
Area is found by multiplying the length by the width.
So you have:
(2x+16) (2x+22) = 832
Use the Foil Method:
(2x+16) (2x+22) = 4x^2 +76x+352
Now you have:
4x^2 +76x+352 = 832
Subtract 832 from both sides:
4x^2 +76x+352-832 = 0
Simplify:
4x^2 +76x -480
Factor the left side:
4(x-5)(x+24) = 0
Divide both sides by 4:
(x-5)(x+24) = 0
Set both parenthesis to equal 0 and solve for x:
x=5 and x = -24
The width of the path cannot be a negative number, so the width is 5 meters.
Hey there!
The answer to your question is
We can see that we are adding two numbers, and the second is , and that is equal to
