5 0

Step-by-step explanation:

-2 (4a + 4b) + 5a > -35

-8a -8b + 5a > -35

-3a -8b > -35

for a

-3a > -35 + 8b

a < -35 + 8b ÷ -3

a < 35 - 8b ÷ 3

for b

-3a - 8b > -35

-8b > -35 + 3a

b < -35 + 3a ÷ -8

b < 35 - 3a ÷ 8

Find the center and radius for the circle, given the equation: x^2-14x+y^2+8=16

Strike441 [17]

You can do this by completing the square

x^2 - 14x + y^2 + 8 = 16

(x - 7)^2 - 49 + (y + 4)^2 - 16 = 16

(x - 7)^2 + (y + 4)^2 = 16 + 16 + 49 = 81

so the center is at (7 , -4) and radius = sqrt81 = 9

To find:

The volume of the rectangular prism.

Solution:

Let the length, breadth and height are 21 in, 20 in and 19 in respectively.

Volume of the rectangular prism is

$V=Length\times Breadth\times Height$

$V=21\times 20\times 19$

$V=7980$

Therefore, the volume of the rectangular prism is 7980 cubic inches.
