Answer:Cullen did not add 4n to the -6n he added -4n.

Step-by-step explanation:When you go to move the -4n you want to add 4n to make the -4n turn to 0. This is because we need n on one side and what it is equaled to on the other.

What occurs when thermal energy is moved from one place to another
sveta [45]
Heat can be moved from one place to another by 3 methods: cunduction, which happends in solids, convection, which happends in fluids, and radiation. Conduction occurs when two objects are touching each other. Heat moves from the hot object to the cold object until the two objects are the same temperature. Convection happends when hotter areas of a liquid or gas rise to the colder areas. Both conduction and convection require some form of matter but radiation does not. Radiation does not rely on things in contact with a heat source and what is being heated. For example, we feel the sun everyday and it feels hot but we never touch it.

Suppose f(x) = x^2. Find the graph of f (x-5). <br> -Graph 1<br> -Graph 2<br> -Graph 3<br> -Graph 4
ohaa [14]

Answer:

x²-10x+25

Step-by-step explanation:

f(x) = x²

<h3>i) substitute the x-5 into x</h3>

f(x-5) = (x-5)²

<h3>ii) using the formula (a-b)² = a²-2ab+b², expand the expression</h3>

f(x-5) = (x-5)²

= x²-2(5x)+5²

<h3>iii) calculate the products</h3>

f(x-5) = x²-2(5x)+5²

= x²-10x+25

* the pic i inserted shows the shape of your graph

The legs of an iscosceles triangle have lengths 3x-1 and -x +27. The base has length 5x+1. What is the length of the base
asambeis [7]

Answer: 36

Step-by-step explanation:

The legs are given to be :

3x - 1 and -x + 27

The base = 5x + 1

One of the properties of an isosceles triangle is that two sides are equal , that is the two legs are equal. This means that

3x - 1 = - x + 27

3x + x = 27 + 1

4x = 28

x = 7

To calculate the length of the base, substitute x = 7 into the length of the base given , that is

Length of the base = 5(7) + 1

L = 35 + 1

L = 36

Two positive consecutive numbers are represented by x and x+1. If four is added to the first
Vesnalui [34]

Answer:

x+4

x+1-2=x-1

Step-by-step explanation:

x+4/x-1=11/16 x should be different than 1 cz 1-1=0

16(x+4)=11(x-1)

16x+64=11x-11

16x-11x=-11-64

5x=-75

x=-15
