Answer:
P(x) = 
Step-by-step explanation:
Root multiplicity of 2 means the root is repeated 2 times. Root multiplicity of 1 means root is repeated only once.
A polynomial of degree 3 means the largest exponent of x is 3.
Here, the polynomial P(x) has root 5 with multiplicity 2 and -5 with multiplicity 1.
So, P(x) = 
Where, 
is a constant.
Now, it's given that the y intercept is -87.5. Therefore, value of x at y intercept is 0.
We obtain by plugging in -87.5 for P(x) and 0 for x.
Therefore, the polynomial P(x) is given as:
Difference means - so 4-(-8)
which also the same as 4+8 so ur answer is 12
Answer:
The two numbers with the sum of 9 and difference of 1 is 5 and 4.

Answer:
Area of Mrs. Rockwell's lot is equal to the area of Mr. Brown's lot
Step-by-step explanation:
We can suppose the dimensions of Mrs. Rockwell's lot to be:
Length = x
Width = y
Then, we can write the dimensions of Mr. Brown's lot as:
Length = half as long as Mrs. Rockwell's lot
Length = 0.5x
Width = twice as wide as Mrs. Rockwell's lot
Width = 2y
Area of Mrs. Rockwell's lot = Length * Width
= x*y
Area of Mrs. Rockwell's lot = xy
Area of Mr. Brown's lot = 0.5x*2y
Area of Mr. Brown's lot = xy
<u>Area of Mrs. Rockwell's lot </u><u>is equal</u><u> to the area of Mr. Brown's lot, as calculated above</u>.
Answer:
10 meters
Step-by-step explanation:
The area of a square is found by
A = s^2 where s is the side length
100 = s^2
Take the square root of each side
sqrt(100) = sqrt(s^2)
10 =s
