The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28
Answer:
x -2 = 3x +2
Step-by-step explanation:
For the purpose, we use math symbols to express the relation described by the English.
<h3>Translation</h3>
When x represents "a number," we have ...
- two less than a number: x -2
- the product of 3 and the number: 3x
- 2 more than the product: 3x +2
- is the same as: =
Then the English description can be translated to ...
x -2 = 3x +2
__
<em>Additional comment</em>
Adding -2-x to both sides gives ...
-4 = 2x
-2 = x . . . . . divide by 2
The number is -2.
Answer:
b(x)=2x+4
Factor out 2.
2(x+2)
EVALUATE
2(x+2)
Step-by-step explanation:
<span>x^2 - 6x = 14
-6
divided by 2 =
-3
then squared =
9
</span><span>x^2 - 6x +9 = 14 +9
(x -3)^2 = 23
answer is B
