If we all draw a triangle using the same three side
lengths, will we all draw exactly the same triangle?
Answer: The triangles will all be the same.
Step-by-step explanation: They might be in different orientation, but they are congruent, and they can be rotated to all match up.
One proof of congruence is "sss" meaning "If the three sides of different triangles are the same, the triangles are congruent."

Step-by-step explanation:
Have a nice day lol i just know things
The equation as a single logarithm is:
[tex]log[(x^2 - 16)/(x + 4)].[/tex]
Option C is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Using the logarithmic identity,
log a - log b = log (a/b)
We can simplify the given expression as:
[tex]=log(x^2 - 16) - log(x + 4) \\= log[(x^2 - 16)/(x + 4)][/tex]
Therefore,
The equation as a single logarithm is:
[tex]log[(x^2 - 16)/(x + 4)].[/tex]

Find the two numbers that have a mean of 12 and a range of 6.
Answer:
9 and 15
Step-by-step explanation:
9 + 15 = 24/ 2 = 12
15 - 9 = 6
The two numbers are 15 and 9.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
Mean of two number is 12 and range is 6.
let the two number be a and b
So, Mean = (a + b)/ 2
12 = (a + b)/ 2
a+ b= 24.........(1)
Now, range = 6
a - b = 6........(2)
Solving equation 1 and 2 we get
2a = 24-6
2a = 18
a= 9
and, b= 24 - 9
b = 15

what is the answer to 5+5(9b - 7)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5+5(9b - 7)
FIRST CASE (JUST EVALUATION)
Given the expression
[tex]5+5\left(9b-7\right)[/tex]
[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac[/tex]
[tex]5+5\left(9b-7\right)=5+5\cdot \:9b-5\cdot \:7[/tex]
[tex]=5+45b-35[/tex]
[tex]= 45b - 30[/tex]
Therefore, we conclude that:
[tex]5+5\left(9b-7\right)=45b-30[/tex]
SECOND CASE (Finding the value of b)
Assuming we have to determine the value of b
[tex]5+5(9b - 7) = 0[/tex]
As we have determined
[tex]5+5\left(9b-7\right)=45b-30[/tex]
so substituting [tex]5+5\left(9b-7\right)=45b-30[/tex] in the equation
[tex]45b-30 = 0[/tex]
Add 30 to both sides
[tex]45b-30+30=0+30[/tex]
Simplify
[tex]45b=30[/tex]
Divide both sides by 45
[tex]\frac{45b}{45}=\frac{30}{45}[/tex]
Simplify
[tex]b=\frac{2}{3}[/tex]
Therefore, the value of b = 2/3

Jerry has been learning to multiply decimals by Integers.
When you multiply an Integer
by 0.01, it's the same as
dividing it by 100.
Is he correct? Prove your answer with examples!
Answer:
Yes
Step-by-step explanation:
Multiplying an integer by 0.01 is the same as Dividing such as :
0.01 = 10^-2
100= 10
For instance :
A number, n = 5 is multiplied by 10^-2
5 * 0.01 = 0.05
Thus, divide the number, n by 100;
5 / 100 = 0.05
Hence, the proof.

Sal purchases a new gaming system and games for $530. The tax is 7%. How much would he spend in taxes only ?
Answer: 37.1
Step-by-step explanation: 530 x .07
Answer:
$37.10
Step-by-step explanation:
You have to take the total price and multiply it by the decimal equivalent of the sales tax. In this case, 7% = 0.07, and so 530 x 0.07 = 37.10. If you wanted to get the total price (for future reference) then you would simply add the tax total to the original price.
