Answer:
4f^2 - r^2 + 3r
Step-by-step explanation:
(4f^2 + 6r + 3) - (r^2 + 3r + 3)
Distribute
4f^2 + 6r + 3 - r^2 - 3r - 3
subtract +3 from -3
4f^2 + 6r - r^2 - 3r
combine like terms
4f^2 + 3r - r^2
rearrange terms
4f^2 - r^2 + 3r
<span>To subtract 3 3/8 from 5 1/2,
by turning into fractions
</span><span>[(5x2)+1]/2 = 11/2
</span><span>[(3x8)+3]/8 = 27/8
</span><span> 11/2 - 27/8
</span>To subtract fractions, your denominator needs to have the same number. so multiply it by 4
44/8 - 27/8 = (44-27)/8 = 17/8.
17 / 8 pounds or 2 and 1/8 because 17 / 8 = 2 remainder 1.
<span>In terms of weight that is 2.125 pounds.</span>
If you make an equation first, 88.72 ≤28+.06m, you can figure it out.
First you subtract 28 from 88.72 getting 60.72≤.06m. Then you divide both sides by .06. Then you get your final answer, which is an inequality, 1012≤m.
That means that Martina uses at least 1012 minutes of service.
I think the answer is x^18 hope this helps
