Let, the width = x
length = 2x - 4
Perimeter = 2(l+w)
Substitute their values,
72 = 2(x+2x-4)
72 = 2(3x-4)
6x - 8 = 72
6x = 80
x = 80/6
x = 13.3
In short, Your Answer would be 13.33 cm
Hope this helps!
Answers:
y intercept = -4
slope = -1
==========================================
Explanation:
The given equation is the same as y = -1x + (-4)
Compare this to y = mx+b form, and we see that
m = -1 is the slope
b = -4 is the y intercept
To graph y = -x-4, you could plot the two points (0,-4) and (1,-5) and draw a straight line through them. Extend the line as far as you can in either direction.
Notice how going from (0,-4) to (1,-5) follows the process "down 1, right 1" which is directly pulled from the slope = -1 = -1/1.
The surface area of prism is 185.815 square inches
<em><u>Solution:</u></em>
Given that,
<em><u>The surface area of package is given as:</u></em>
Where,
"l" is the length
"w" is the width
"h" is the height
<em><u>Substituting the values we get,</u></em>
Thus the surface area of prism is 185.815 square inches
Answer:
C
Step-by-step explanation:
7 - 2 = 5
11 - 3(2)
11 - 6 = 5
4(2) - 3
8 - 3 = 5
C is the only one that doesn't equal 5
3y+4y+6=20
(3y+4y)+(6)=20
(Combine Like Terms)
7y+6=20
7y+6=20
Subtract 6 from both sides.
7y + 6 − 6 = 20 − 6
7y = 14
Divide both sides by 7.
7y/7 = 14/7
y = 2
