Answer:
x is equal to 2.5 and -4.5
Step-by-step explanation:
-4(x + 1)² - 3 = -51
-4(x² + 2x + 1) - 3 = -51
-4x² - 8x -3 - 3 = -51
-4x² - 8x - 6 = -51
-4x² - 8x = -45
-4(x^2 + 2x) = -45
-4(x^2 + 2x + 1) = -49
-4(x + 1)² = -49
(x + 1)² = 49/4
x + 1 = ± √(49/4)
x + 1 = ± 7/2
x = -1 ± 3.5
x = 2.5, -4.5

Amy and Belinda each roll a sheet of 6-inch by 8-inch paper to form a cylindrical tube. Amy tapes the two 8-inch sides together without overlap. Belinda tapes the two 6-inch sides together without overlap. What is $\pi$ times the positive difference of the volumes of the two tubes
Answer:
ΔV = 24*π inches
Step-by-step explanation:
Amy Tube volume = V₁ the 6 inches sides will shape the circumference of area A₁ = π*r²
A₁ = π*(3)² and
V₁ = π*r²*h₁
V₁ = π*(3)²*8
V₁ = 72*π
In the case of Belinda, r will be 4 inches and h₂ = 6 and V₂
V₂ = A₂*h₂
V₂ = π*(4)²*6
V₂ = 96* π
Then differences of the volumes is
V₂ - V₁ = ΔV = 96*π - 72*π
ΔV = 24*π inches

Four points are always coplanar if they:
Four points are always coplanar if they: lie in same plane.
Firstly understanding the coplanar points. Coplanar points are refers to the points if they are present in same plane. Further defining the word "plane". Plane is the surface, which is flat and two dimensional in nature. The surface is infinite. Plane can also be referred as the analogue of 3 dimensional space, you we can also interpret the plane as extension of point or line.
So, the points that lie on different planes will not be coplanar. Now, understanding the points on lines. Two or more lines may or may not be in same plane. Subsequently, points may or may not be coplanar, depending upon the lines they are placed on. Thus, we can not definitely say that points lying on the same line are coplanar.

three coworkers decided to buy fruit to share at lunch time.Antonii spent $1.47 on bananas.Laura spent $2.88 on apples.Suzanne spent $2.85 on oranges.
If Laura bought 2.1 pounds of apples,is the price per pound of apples greater than or less than $1 ? how can you tell?
Answer:
The price per pound of apples is greater than $1.
Step-by-step explanation:
Please consider the complete question:
Three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, is the price per pound of apples greater than or less than $1 ? how can you tell?
To find the price of apples per pound, we need to divide total amount paid by Laura ($2.88) with total pounds of apples (2.1 pounds) bought.
Price of apple per pound = [tex]\frac{2.88}{2.1}[/tex]
Price of apple per pound = $1.37142857
Since the price of apples per pound is $1.37, therefore, the price per pound of apples is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1. So when we will divide 2.88 by 2.1, then we will get a number greater than 1.
Using unitary method, the price per pound of apples is greater than $1.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that three coworkers decided to buy fruit to share at lunch time. Antonii spent $1.47 on bananas.Laura spent $2.88 on apples. Suzanne spent $2.85 on oranges. If Laura bought 2.1 pounds of apples, then
To determine the price of apples per pound, we need to divide total amount paid by Laura with total pounds of apples bought.
Price of apple per pound = 2.88/ 2.1
Price of apple per pound = $1.37142857
Since the price of apples per pound is $1.37, thus, the price per pound is greater than $1.
We can simply tell that the price per pound of apples is greater than $1 because 2.88 is greater than 2.1.

Angelica the Alligator is laying our next to a perfectly circular pond. She is 9 feet from the edge of the pond and 15 feet from the point of tangency. Determine the radius of the pond.
9514 1404 393
Answer:
8 ft
Step-by-step explanation:
Consider the attached diagram.
The rule for secants and tangents tells us ...
(AC)(AB) = (AT)²
AC = AT²/AB = 15²/9 = 25
Then the diameter is ...
BC = AB - AC = 25 -9 = 16
The pond has a diameter of 16 ft, so a radius of 8 feet.
__
Additional comment
Since point C is the nearest point on the edge of the pond to point A, it must lie on line AO. Hence BC must be a diameter.
