Step-by-step explanation:
<u><em>⇒ Given info:</em></u>
<em>Factor completely </em>![x^2 -64](https://tex.z-dn.net/?f=x%5E2%20-64)
<u><em>⇒ Solution:</em></u>
<em>Rewrite 64 as 8 ² because 8² is equal to 64. 8 ² = 8 × 8 = 64.</em>
<em />![=x^2-8^2](https://tex.z-dn.net/?f=%3Dx%5E2-8%5E2)
Applying difference of two squares formula: ![x^2-y^2=\left(x+y\right)\left(x-y\right)](https://tex.z-dn.net/?f=x%5E2-y%5E2%3D%5Cleft%28x%2By%5Cright%29%5Cleft%28x-y%5Cright%29)
![=x^2-8^2=\left(x+8\right)\left(x-8\right)\\](https://tex.z-dn.net/?f=%3Dx%5E2-8%5E2%3D%5Cleft%28x%2B8%5Cright%29%5Cleft%28x-8%5Cright%29%5C%5C)

Answer:
![x=34](https://tex.z-dn.net/?f=x%3D34)
Step-by-step explanation:
*it's kind of hard to read the number in parenthesis though but i think it's 5
both angles have to add up to 180º because they are co-exterior angles on parallel lines.
![2(x+5)+102=180\\2(x+5)=78\\2x+10=78\\2x=68\\x=34](https://tex.z-dn.net/?f=2%28x%2B5%29%2B102%3D180%5C%5C2%28x%2B5%29%3D78%5C%5C2x%2B10%3D78%5C%5C2x%3D68%5C%5Cx%3D34)
Answer:
t(c) = 3.355
Step-by-step explanation:
We assume a normal distribution, and with sample size n = 9 we should follow a t -student test on both tails since the FDA is interested in determining if the amount of drug absorbed is different from 3.5 micrograms.
Therefore if α = 0,01 that means that confidence interval is 99 % or 0,99
Finally with α/2 = 0,005 and 8 degrees of freedom we find in t-student table t(c) = 3.355
Given:
<span>F= $335,000
n = 30 years at a fixed rate of i = 7.5%
Required:
the total cost of the principal
Solution:
F = P(1+i)^n
P = F/(1+i)^n
P = 335,000 / (1.0.075)^30
P = 38,264.05</span>
Well cutting off the small 4x2 you get 8 plus’s the 7x2 is 14 so just add those together you should get 22in ^2
