A rectangle has a perimeter of 30 inches.one side measures 5 inches.what of the measures of the three sides ?
cluponka [151]
I believe since the definition of perimeter is adding the lengths of all three sides of the angles the, width of the rectangle would be 5, and the length of the rectangle would be 10.

  10
+10 
-------
 20
+5
------
  25
+5
------
30 

And that is you answer, yay!

Please explain each step 5x-7=7x-17
EleoNora [17]
Let's get the same terms on the same side.
I am going to remove 5x from both sides of the equation by subtracting 5x

5x - 5x<span> -7 = 7x -</span>5x<span> - 17</span>
           -7 = 2x - 17   now lets remove the 17 from both sides
       -7 + 17 = 2x     (why do we add 17?  Think of 2x -17 as 2x +  -17.  Tor remove a negative number we add it.
Now we finally have     10=2x and if we divide both sides by 2

<u>10</u><span>  = </span><u>2x</u><u>
</u>2       2    we get that x = 5
<u />Let's check by substituting 5 in the original equation:
5(5) - 7 = 7(5) - 17
25 - 7 = 35 - 17
<span>18      =       18</span>

Number 13 please thanks

Answer:

(3, - 9)

Step-by-step explanation:

Differentiate using the power rule

y = ax^{n} , then

\frac{dy}{dx} = nax^{n-1}

Given

y = x² - 6x

\frac{dy}{dx} = 2x - 6

Equate to zero since the measure of gradient is \frac{dy}{dx} , that is

2x - 6 = 0 ( add 6 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into y for corresponding value of y

y = 3² - 6(3) = 9 - 18 = - 9, thus

(3, - 9 ) are the coordinates of the point where the gradient is zero
