<span>4p - 5 • (p + 6)
</span>-p - 30 = -1 • (p + 30)<span>
</span>
<span> -p - 30</span>
5/8 would be the simplest form for 10/16 .
Answer:
Step-by-step explanation:
a+pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
a= 353.25ft^2
Answer:
12/5
Step-by-step explanation:
All you do is multiply
Answer: k=9/4
Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:
>x^2 +3x +9/4
> (x+3/2)(x+3/2)
Perfect square.
