1. Factor by grouping: (16x^2+20x)(20x+25)
2. 4x(4x+5)+5(4x+5)
3. (4x+5)(4x+5)
4. (4x+5)^2
Answer:
see first of all it is a quadratic polynomial so it will have 2 zero alpha and beta
now , we will find value of a , b, c
so,
a= 3
b= 5
c= -2
now, sum of the zeros ( alpha + beta) =-b/a
so,-5/3
now product of zeros (alpha *beta) = c/a
so, it will we -2/3
hope you get it !
Answer:
From Tuesday to Thursday, the total change in the value of the stock was $-0.36.
There are 3 days from the opening of the stock market on Tuesday and the close of the stock market on Thursday.
The average change in the value of the stock from the opening of the stock market on Tuesday and the close of the stock market on Thursday is $-0.12 per day. This means the stock this amount each day on average.

Answer:
c = 30.56 to the nearest hundredth
Step-by-step explanation:
87 = 9/5 c + 32
87 - 32 = 9/5 c
9/5 c = 55
multiply both sides by 5/9:
c = 55*5 / 9
c = 30.56.
