2 - (2t + 1) = 4(t + 2)

First you want to distribute the 4 on the right side to everything in the brackets by multiplying both terms by 4

2 - (2t + 1) = 4t + 8

Then you want to add (2t + 1) to both sides

2 = 4t + 8 + (2t + 1)

Now you can get rid of the brackets

2 = 4t + 8 + 2t + 1

Simplify

2 = 6t + 9

Minus 9 on both sides

-7 = 6t

Divide by 6 on both sides

-1.17 = t

What is the vertex of the graph of y = −1(x − 2)2 + 3
Alona [7]

Vertex: \ (2,3)

<h2>Explanation:</h2>

The vertex form of the equation of a parabola is given by the following form:

f(x)=a(x-h)^2+k \\ \\ Where: \\ \\ a:Leading \ Coefficient \\ \\ (h,k):Vertex \ of \ the \ parabola

In this exercise, we have the following equation:

y=-(x-2)^2+3

From here, we can conclude that:

Leading \ coefficient: \ -1 \\ \\ Vertex: \ (2,3)

Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.

A gift box is in the shape of a trapezoidal prism with base lengths of 7 inches and 5 inches and a height of 4 inches. The heigh
jek_recluse [69]
First of all there are multiple formula's to get the volume of a trapezoidal prism:

V=(1/2 * (base1 + base2) * h) * height prism

Using the numbers you gave: 
base1 = 7     base2 = 5     h = 4     height prism = 8

Putting this into the equation:  V=(1/2 * (7 <span>+ 5) * 4) * 8
V= (1/2 * 12 * 4) * 8
V = 24 * 8
V = 192

The volume of the gift box is 191 inches squared.</span>

a container of candy is shaped like a cylinder and has a volume of 125.6 cubic centimeters. If the heights of the container is 1
Elenna [48]

The radius of the container is 2 centimeter

<h3><u>Solution:</u></h3>

Given that a container of candy is shaped like a cylinder

Given that volume = 125.6 cubic centimeters

Height of conatiner = 10 centimeter

To find: radius of the container

We can use volume of cylinder formula and obatin the radius value

<em><u>The volume of cylinder is given as:</u></em>

\text {volume of cylinder }=\pi r^{2} h

Where "r" is the radius of cylinder

"h" is the height of cylinder and \pi is constant has value 3.14

Substituting the values in formula, we get

\begin{array}{l}{125.6=3.14 \times r^{2} \times 10} \\\\ {r^{2}=\frac{125.6}{31.4}} \\\\ {r^{2}=4}\end{array}

Taking square root on both sides,

r = \sqrt{4}\\\\r = 2

Thus the radius of the container is 2 centimeter
