Solve the equation for x, in simplest form. x + 3 8 = 1 4 A) x = 1 8 B) x = 1 6 C) x = − 1 8 D) x = − 1 6

x = -1/8

Step-by-step explanation:

x + 3/8 = 1/4

Get a common denominator

x + 3/8 = 1/4*2/2

x + 3/8 = 2/8

Subtract 3/8 from each side

x+3/8 -3/8 = 2/8 -3/8

x = -1/8

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

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
