The answer would be B. Heptagon.
2x - y = 5 = http://www.algebra.com/algebra/homework/Graphs/Graphs.faq.question.141166.html
18x + 20 + x = 10x -3
Combine like terms
19x + 20 = 10x -3
Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:
19x = 10x -23
Subtract 10x
9x = -23
Divide 9 to isolate x:
x = -23/9
Simplify to get a mixed number:
x = -2 5/9
Answer:
yes alby is correct
Step-by-step explanation:
Answer:
x^2 -6x +6
Step-by-step explanation:
<em>Square of a difference (can be found in IM2)</em>
Formula: a^2 -2ab +b^2
x= a; 3= b
(x -3)(x -3)
<em>Plug in to formula.</em>
x^2 -2(x)(3) +3^2
<em>Simplify.</em>
x^2 -6x +6
