1st Question: 
the answer is 85 because the angle measure does not change even if you rotate the figure.
2nd Question:
The answer is A) reflection across y-axis and translation 7 units down 
3rd Question:
The first answer choice is correct because the figure increases/decreases in length on all side lengths and the angle measures stay the same.
Question 10: (on the test online)
The answer is 12*6 or 72 because 30 (a'b') / 5 (ab) is 6 giving you the scale factor for the dilation.
Question 11:
The answer is a dilation
Question 12: 
The answer is a dilation and a translation because you first increase the size of the figure then move it down and to the right.

Use the integer tiles to evaluate the following expressions. 6 + 3 = 6 + (–4) = 6 + (–6) =
babunello [35]

Given:

The expressions are:

6+3

6+(-4)

6+(-6)

To find:

The value of given expression by using integer tiles.

Solution:

We have,

6+3

Here, both number are positive. When we add 6 and 3 positive integer tiles, we get 9 positive integer tiles as shown in the below figure. So,

6+3=9

Similarly,

6+(-4)

Here, 6 is positive and -4 is negative. It means we have 6 positive integer tiles and 4 negative integer tiles.

When we cancel the positive and negative integer tiles, we get 2 positive integer tiles as shown in the below figure. So,

6+(-4)=2

6+(-6)

Here, 6 is positive and -6 is negative. It means we have 6 positive integer tiles and 6 negative integer tiles.

When we cancel the positive and negative integer tiles, we get 0 integer tiles as shown in the below figure. So,

6+(-6)=0

Therefore, 6+3=9, 6+(-4)=2,6+(-6)=0.

What can you tell about a triangle when given three side lengths?
Genrish500 [490]
Check whether it is possible to have a triangle with the given side lengths for example 7,9,13 then add any two sides and see if it is greater than the other side. Example the sum of 7 and 9 is 16 and 16 is greater than 13

Select the correct answer.
ratelena [41]

Answer:

A.x(x+12) -7(x+12)

Step-by-step explanation:

Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

x^2 +5x - 84

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

x^2 +12x - 7x - 84

Now take out the common factors,

x(x+12) -7(x+12)

Thus, the correct option is choice (A).
