Step-by-step explanation:
I'm pretty sure this is correct
Question #4 = 7.8
Question #5 = 17
The minimum value for x is -1 so y = -5 to x<0 , y<-2
maximum value for x is 0 so y =3
the range is ]-5,-2[ + {3}
Answer:
The area of the rectangle is 2820 square inches. The length is 60 inches. The width is 47 inches.
Step-by-step explanation:
Since we know the equation to find the width, we have to set them both to the perimeter of 90 inches. We will use the variable <em>x</em> to represent the length.
<em>x + x - 30 = 90</em>
<em>2x - 30 = 90</em>
<em />
You would then subtract 30 from both sides.
<em>2x = 60</em>
Divide by 2 on both sides, finding that the length (x) is 30 inches.
<em> x = 30 inches.</em>
<em></em>
Then, subtract 13 inches from the length to find your width.
<em>60 - 13 = 47 inches</em>
<em />
To find your area, you would multiply both of your factors (length and width) together.
<em> 60 x 47 = 2,820</em>
<em />
And those are your answers!
