It’s a bc:AB and BC don’t form a line and share an endpoint
First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x
Now you may subtract those two
7-4x= 3x
Step-by-step explanation:
A polyhedron include cube ,prism or pyramid while non polyhedron are sphere, cone and cylinder because they have side that aren't polygon. a prism is a polyhedron with two congruent base ,in parallel planes and the lateral sides are rectangle
Well let's convert 2/3 to fraction of 6ths, by multiplying top and bottom by 2
<em>Answer:</em>
<em>(r + 9)(r - 3)</em>
<em>Step-by-step explanation:</em>
<em>r² + 6r - 27 =</em>
<em>= r² + 9r - 3r - 27</em>
<em>= r(r + 9) - 3(r + 9)</em>
<em>= (r + 9)(r - 3)</em>
