Answer:
Length = 5
Width = 21
Step-by-step explanation:
(x)(x + 16) = 105
x^2 + 16x = 105
x^2 + 16x - 105 = 0
(x - 5) x ( x + 21) = 0
x - 10 = 0
x = 5
x + 21 = 0
x = -21
Now that we have the zeroes.
We have to find the most viable one to put in.
Using -21 would not make sense, so we will use 5.
Plug it in:
x = 5
(5) (5 + 16) = 105
5 ( 21) = 105
Answer: 0.5

Multiplicity is how many times each root repeats
(x-r1) where r1 is the root
root is 1 of multiplicity 2 means
(x-1)^2
root -2 multiplicity 3 means
(x+2)^3
so the function is
(x-1)^2(x+2)^3
f(x)=(x-1)^2(x+2)^3
expanded
f(x)=

(x-1)^2(x+2)^3
Its in the hundreths place
Answer:
a ( copper and nickel
b ( 1034.9
Step-by-step explanation:
Add all the values of melting points
2,651 + -37.89 = 2613.11
2613 + -458 = 2155.11
2155.11 + 1984.32 = 4139.43
Divide the number by the number of numbers: 4139.43/4 = 1034.8575
1034.8575 rounded to the nearest tenth is 1034.9, thats how you find the mean, or the average.
