Parallelograms have opposite sides that are equal, so you can set BC and AD equal to each other to find the value of x if the figure is a parallelogram. 
x + 3 = 2x - 1
3 = x - 1
4 = x

Now check
4 + 3 = 2(4) - 1
7 = 7

The value of x that makes ABCD a parallelogram is x = 4.

Hope this helps =)

Math- Differentiation . Could you help me to solve this question?
Arlecino [84]

Answer:

Step-by-step explanation:

Hello, first of all we can find a value for f(1)

xf(x)+f(x^2)=2 \\\\\text{So for x = 1, it gives}\\\\f(1)+f(1^2)=f(1)+f(1)=2f(1)=2\\\\ f(1) =1

And we can get the derivative of the equation so.

(uv)'=u'v+uv' \text{ and } \dfrac{df(x^2)}{dx}=2xf'(x^2) \text{ so we can write}\\\\f(x)+xf'(x)+2xf'(x^2)=0\\\\\text{And then, for x = 1}\\\\f(1)+f'(1)+2f'(1)=0\\\\ f(1)+3f'(1)=0\\\\ 3f'(1)=-f(1)=-1\\\\\large \boxed{ f'(1)=-\dfrac{1}{3} }

Thank you

PLEASE HELP!!! 20 POINTS WILL BE GIVEN!
77julia77 [94]
SI = PRT /100

1. SI = 400*5*1/100
        = 2000/100
        = $ 20

2. SI = 1000*8.5*3/100
        = 25.5*1000/100
        = $ 255

3.  SI = 200*9*1/2*100
         = 900/100
         = $9

4.  SI = 20000*12*3/100
         = 200*12*3
         = 7200

5.  SI = 1200*4.5*6/12*100
         = 4.5*6
         = $27
  
Amount to pay = Principal + SI
                        = 1200+27
                        = $1227 ( But this answer isn't there in the options )
