In 1. the graph would open down because of the negative sign in front of the 2. The 2 in front of the x, would excel the growth of the graph by a factor of 2, making it more narrow.
on the second problem the -5, being that it is tied to the x and being squared and inside of the (), would cause the graph to shift 5 units to the right (always opposite of the sign in front of the number.
3 3/4 lb of candy costs $ 20.25
we have been given a mixed fraction with both whole number and fraction

Step-by-step explanation:
(√3+√7)²
We know ,[(a+b)²=a²+2ab+b²]
=>(√3+√7)²=(√3)²+2(√3)(√7)+(√7)²
=>(√3+√7)²=3+2√21+7
=>(√3+√7)²=10+2√21
