Which equation shows equivalent forms of the expression 21 x 2-4 ? 2^1 ×2^−4 =2^−4=−8 2^1 ×2^−4 =2^−4=1/2^4=18 2^1 ×2^−4 =2^−3=1/2^3=18 2^1 ×2^−4 =2^−3=−8

Used:

2^1 × 2^-4 = 2^-3 = 1/2^3 = 1/8

in 4 days he will run   12/14

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
