Answer:
x° = 67°
Step-by-step explanation:
1. The first three diagrams are showing you that opposite exterior angles are congruent. Based on that, when you are faced with opposite exterior angles in the fourth diagram, you are able to conclude they are congruent. That means x° = 67°.
2. You can determine the other angles in the figure based on linear angles being supplementary, and same-side interior angles being supplementary. After you work through all the angles, you find that x = 67.
Answer:
7 - x meters
Step-by-step explanation:
This is a difference of squares. The formula for difference of squares is
a^2-b^2 = (a-b)(a+b)
So plug the numbers we know into this formula.
Area = lw
49 - x^2 = (a-b)(7+x)
49 - x^2 = (7-x)(7+x)
<u>The length is 7 - x meters.</u>
Answer:
$7150
Step-by-step explanation:
To find how much is earned, take the amount earned per week times the number of weeks
275*26 =7150
Answer: First option.
Step-by-step explanation:
You need to remember that to factorize the given expression
, you need to choose two numbers that when you add them you get "10" and when you multiply them you get "21".
These number are:
7 and 3
Because:

Therefore, you get that the factorization of the expression
is the following:

You can observe that this factorization matches with the first option.
