Answer:
they are unlike term
in order for terms to be alike they need to have the same exponent x on the left doesn't have a power while the one the right has a power of 2 as with the y
Answer:
15r²-14r-8
Step-by-step explanation:
Use FOIL for this:
(5r+2)(3r-4)
First: 5r × 3r = 15r²
Outer: 5r × (-4) = -20r
Inner: 2 × 3r = 6r
Last: 2 × (-4) = -8
15r²-20r+6r-8=
15r²-14r-8

The number of ways that Grant can arrange 3 of the 10 plants is<u> 120 ways</u> and the number of ways that 4 floats out of 8 can be arranged is 70 ways.
<h3 /><h3>How can these combination problems be solved?</h3>
Grant can arrange 3 out of 10 plants in the following number of ways:
= 10!/ ((10! - 3!)3!)
= ( 10 x 9 x 8) / (3 x 2)
= 120 ways
The parade organizer can arrange 4 floats out of 8 as:
= 8!/((8! - 4!)4!)
= (8 x 7 x 6 x 5) / (4 x 3 x 2)
= 70 ways
When 4! is written in expanded form, it comes out as:
= (4 x 3 x 2)
