Given the polynomial expression:
(y + 5)²
(y - 5)(y + 5)
Let's simplify each of the given expression:
a.) (y + 5)²
The given equation is a factor of a perfect square trinomial. For this type of expression, the following is the formula for expanding it.
We get,
b.) (y - 5)(y + 5)
To be able to simplify the following expression. We will be using the formula for the difference of two squares.
We get,
L(t)=9-0.5t
t=time in hours,
L(t)=length of candle at time t
(A) substitute t=1,2,3,4,5,6 respectively to get
(1,8.5)
(2,8)
(3,7.5)
(4,7)
(5,6.5)
(6,6)
(B) it is a function because none of the x-values duplicate, (nor the y-values).
(C) If the rate changes to 0.45 "/hr, the relation is still linear.
All linear function with finite slope are functions.

What are the coefficients in the polynomial 4x²+3x-3?
<u>Coefficient:-</u> A number before a variable
<u>Coefficients in this polynomial:-</u>
4 (the number before x²) and 3 (the number before x)
<h3 />
So we conclude that the right option is:-
4, 3 (Option B)
<h3>Good luck.</h3>

Answer:
Step-by-step explanation:
<u>Properties of a parallelogram</u>
- Two adjacent angles are supplementary
- Opposite angles are congruent
- Opposite sides are parallel and congruent
Use the properties to find the required parameters
1) <u>Find m∠YXV</u>
- m∠YXV + m∠VXW + m∠VWX = 180°
- m∠YXV + 40° + 84° = 180°
- m∠YXV = 180° - 124°
- m∠YXV = 56°
2) <u>Find m∠Y</u>
3) <u>Find x</u>
So the formula for a volume of a sphere is 4/3 times pi times the radius cubed.
step one: 4/3 times 3.14 = 4.18666666667
Step two: then you cube 8.5 and get 592.45
the final answer is 2,480.3906
