Answer:
A
Step-by-step explanation:
We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.
Here, the length is l = x and the width is w = x + 3. So, plug these in:
A = lw
A = x(x + 3)
Expand this out:
A = x² + 3x
The answer is thus A.
<h3>Answer:</h3>
c) there are infinitely many solutions
<h3>Explanation:</h3>
Add x to the <em>first equation</em> to put it in standard form:
... x + y = 3
Divide the <em>second equation</em> by the common factor of all terms, 2, to put it in standard form:
... x + y = 3
These two equations describe the same line. Every point on the line is a solution to both equations, so there are infinitely many solutions. (We say these equations are "dependent.")
Im assuming by 5-.8, you mean 5/8ths and by 1-.4, you mean 1/4th...
x=5/8+1/4
x=5/8+2/8
x=7/8
They ate 7/8 together
Point 1: (-3, 7)
Point 2: (-17, 3)
To find the slope, we need to use the slope formula which is as follows: m = (y2 - y1) / (x2 - x1). We will plug in each x and y coordinate from our points above, respectively.
m = (3 - 7) / (-17 - - 3)
m = (-4) / (-14)
m = 2/7
The slope of the line that goes through (-3, 7) and (-17, 3) is 2/7.
Hope this helps!! :)
The expression would be > 0.
Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0. Since we know that x>-18, 0 is below anything we could get from this.
