Move the 6 to the other side:
2x^2 +x+6,
(x-3) (x+4)
x=3 and x=-4
C i think, sorry if its wrong
(2.6x7)/2
18.2/2
Area=9.1 m^2
Answer:
<h2>x=29</h2>
Step-by-step explanation:
<h3>to understand the solving steps</h3><h3>you need to know about:</h3>
- right angle
- equation
- PEMDAS
<h3>to solve:</h3><h3>x</h3><h3>let's solve:</h3>
<u>a </u><u>right</u><u> angle</u><u> </u><u>contains </u><u>9</u><u>0</u><u>°</u> (always)
according to the question
x+3+x-1+x+1=90
3x3=90
x=87
x=29
<h2>solved</h2>
The answer is 127.16 pi m³, hope this helps.
