How do you solve (2x + 8 )2 =64

Mathematics
1 answer:
Drupady [299]3 years ago
4 0

Answer:

x = 12

Step-by-step explanation:

  1. Write in a different way: 2(2x + 8) = 64
  2. Apply the distributed property, so it now looks like this: 4x + 16 = 64
  3. Subtract 16 from each side, so it now looks like this: 4x = 48
  4. Divide each side by 4 to cancel out the 4 next to x. It should now look like this: x = 12

I hope this helps!

The average high temperature during the hottest month in Beijing, China, is 72°F. The average high temperature during the coldes
Angelina_Jolie [31]

Answer:

- September

Step-by-step explanation:

The temperature in Beijing, in m months after January, is given by the following equation:

T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45

In which m is the number of months after January.

During which month in the year would the temperature reach 55°F?

We have to find m for which: T(m) = 55. So

T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45

55 = 27\cos{((\frac{\pi}{6})(m-6))} + 45

27\cos{((\frac{\pi}{6})(m-6))} = 10

\cos{((\frac{\pi}{6})(m-6))} = \frac{10}{27}

Now, we apply the inverse cosine, on both sides of the equation, to find the value of m.

\cos^{-1}{\cos{(\frac{\pi}{6})(m-6)}} = \cos^{-1}{\frac{10}{27}}

Now, with the help of a calculator, in radians:

\frac{\pi}{6}(m-6) = 1.19

\pi m - 6\pi = 6*1.19

\pi m = 6*1.19 + 6 \pi

m = \frac{6*1.19 + 6 \pi}{\pi}

m = 8.27

8.27 months after January, since 8.27 + 1 = 9.28, it happens during the month of September.
