Width=20.108 yrd and Length=43.216 yrd
Step-by-step explanation:
Let width = w
Length =3+2w
Area = 869 yrd^2
We need to find length and width of rectangle.
The formula used is:
Putting values:
Using quadratic equation to find value of width w:
a=2, b=3 and c=-869
Since width can't be negative so, width w=20.108
Length will be: L=3+2w = 3+2(20.108)=3+40.216=43.216
So, Width=20.108 yrd and Length=43.216 yrd

Answer:
The remaining solutions are -7 and 3.
Step-by-step explanation:
The synthetic division is shown in the attachment. After dividing the first two found factors from the polynomial, the remaining quadratic is ...
x^2 +4x -21 = 0
Its rational roots will be factors of -21, and the sum of their opposites will be 4. Knowing that 21 = 3·7, we can guess that the remaining roots are -7 and 3. The synthetic division confirms that. (A graph also confirms it.)

A double replacement reaction occurs when the ionic parts of two ionic compounds are exchanged.
Reaction 1 results in a product which is a single compound. No ionic parts are exchanged.
Reaction 3 results in one compound being separated into its elemental parts. No ionic parts are exchanged.
Reaction 4 has two reactants, but Pb is an element and not an ionic compound. No ionic parts are exchanged.
Hence, the answer is Reaction 2. Both NaBr and Ca(OH)2 are ionic compounds. Br - is the anion in NaBr, and (OH)2 is also an anion. Ionic parts are exchanged.
Answer:
24
Step-by-step explanation:
2.5 divided by 2.5 equals 1. So 60 divided by 2.5 equals 24.
