What is the answer to (3x+17)+ (5x-3)=180

20.75

Step-by-step explanation:

(3x + 17) + (5x - 3) = 180

add variables and numbers

3x + 5x + 17 - 3

8x + 14 = 180

subtract 14

8x = 166

divide by 8

8/8x = 20.75

x = 20.75

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
