Answer:
x = 20
Step-by-step explanation:
If a line is parallel to a side of a triangle and it intersects the other two sides then it divides those sides proportionally.
This is the case here thus
=
( cross- multiply )
11(5x + 10) = 1210
55x + 110 = 1210 ( subtract 110 from both sides )
55x = 1100 ( divide both sides by 55 )
x = 20
45 per 3 hours! :) hope this is good
The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.
