<span>(6k+10) (4k+5) is not an equation. Or, did you unintentionally leave off "=0?"
Thus, we cannot find a value for k.
If we set </span><span>(6k+10) (4k+5) = to 0, then the roots would be solutions of 6k+10=0 and 4k+5=0. They are {-5/3, -5/4}</span>
6 and 30. 6 is 1/5 of thirty. If the first number is x,that means that the second number is 5x. Combine like terms. 6x = 36. 36/6 = 6. x = 6. The first number is 6. the second number is 5x. Replace x with 6. 5 * 6 = 30. 30 is the second number.
Answer:
x = 4
Step-by-step explanation:
4(6x+1) +4 =104
-4 -4
4(6x+1) = 100
distribute
24x + 4 = 100
-4 -4
24x = 96
x = 4
To check your work, substitute the x value into the equation.
4(6(4)+1) +4 =104
4(25) + 4 = 104
104 = 104
It is correct, one solution.
(new -original)/original * 100
(36-20)/20 * 100
16/20 * 100
.8*100
80
80% increase
Step-by-step explanation: Since the width and length are consecutive odd integers, call the width <em>x</em> and the length <em>x + 2</em>.
Now, it would be helpful to draw a picture of your rectangle
and label its parts to help you set up the equation.
Since the perimeter of the rectangle is 120 meters,
<em>x + x + (x + 2) + (x + 2) = 120</em>.
Simplifying from here we get 4x + 4 = 120.
Now subtract 4 from both sides to get 4x = 116.
Now divide both sides by 4 to get x = 29.
So the width of our rectangle is 29 meters
and the length, <em>x + 2</em>, is 31 meters,
