Use the number line to add the fraction. Pls helppp
PtichkaEL [24]

Answer: 1/6

-1/2 also equals -3/6

2/3 also equals 4/6

Using the number line, start at -1/2. Then, since the distance from one dash to the next on the line equals 1/6, you will move 4 spaces to the right. That should give you 1/6.

Please help me with this<br> simplify sqrt24w^14
Serjik [45]

Answer:

2×sqrt(6)×w⁷

Step-by-step explanation:

what I can read here, you need to simplify

sqrt(24×w¹⁴)

= sqrt(24)×sqrt(w¹⁴) = sqrt(4×6)×sqrt(w¹⁴) =

= 2×sqrt(6)×sqrt(w¹⁴)

and taking the square root of something with exponent simply means dividing that exponent by 2

so,

2×sqrt(6)×w⁷
