Answer:

A. 42 and 14

Step-by-step explanation:

first number = x

second number = y

x - y = 28

3x - x = 28

(y is now x because it says the second number is whatever x was, but three times less)

x = 14

3(14) - (14) = the original number, 28

3c^2 - 8c + 5 = 3c^2 - 3c - 5c + 5 = 3c(c - 1) - 5(c - 1) = (3c - 5)(c - 1)

What is the area of the shaded region?

saveliy_v [14]

Answer:

Answer is 330

Step-by-step explanation:

$area \: of \: shaded \: region \: = \pi {r}^{2} - \pi( {x}^{2} \\ here \: r = 11 \: cm \: and \: x = 4 \: cm \\ area \: of \: a \\ shaded \: regoin \: = \pi( {r}^{2} - {x}^{2} ) \\ = \pi( {11}^{2} - {4}^{2} ) \\ = \pi(121 - 16) \\ = \pi(105) \\ = \frac{22}{7} \times 105 \\ = 22 \times 15 \\ = 330 \: {cm}^{2}$

AREA OF SHADED REGION =330
