Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Anna [14]
The shaded areas add to 2/5 of the area of the circle, which is given by
  A = πr²

Then the shaded area is ...
  (2/5)A = (2/5)π(10 in)²
  shaded area = 40π in²

Solve for x. And graph 7(3x+4)+2&lt;156
blsea [12.9K]

7(3 \times x + 4) + 2 < 156 \\ 21 \times x + 28 + 2 < 156 \\ 21 \times x + 30 < 156 \\ 21 \times x < 156 - 30 \\ 21 \times x < 126 \\ x  <   \frac{126}{21}  \\ x < 6

TiliK225 [7]

Answer:

100

Step-by-step explanation:

4\times(2+3)^{2}

This can be turned into:

4\times5^{2}  (if we add the numbers inside the brackets)

Following PEDMAS, this becomes:

4\times25 which equals 100

∴  4\times(2+3)^{2}=100
