$7.9 cost of one pack
10 packs cost is $79
She pays $29 + Voucher
From the total $79 we substract the $29 she paid with cash or card.
79-29=50
So the value of the voucher is $50

Answer:
x= 56
Step-by-step explanation:
86+94= 180 which if supplementary angles have to equal 180°
I don't know if you can tell but what's in red means distribute
then I added 26 on both sides with like terms
on the left side 86+26=112 and right side is left with 2x
then divide both sides by 2 to leave x by itself
112/2= 56 and 2x/2=x
so 56=x
 
        
             
        
        
        
Answer:
y = (x+3)^2 -1
Step-by-step explanation:
The vertex form of the equation is 
y = a(x-h)^2 +k  where (h,k) is the vertex
The vertex is (-3,-1)
y = a(x- -3)^2 -1
y = a(x+3)^2 -1
Pick another point  (-2,0) and substitute it into the equation
0 = a(-2+3)^2 -1  to find a
0 =a(1)^2 -1
0 = a-1
1 = a
y = (x+3)^2 -1

The correct option is b. No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
<h3>How to explain the information?</h3>
The figure is a parallelogram and one diagonal measure 28 units.
In this case, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
Therefore, the correct option is B.
