Use the distributive law to compute each of the following expresssions. a.38 x 102
b,95 x 64
a.107 x 49
b.73 x 98
a.(69 x 15)+(31 x 15)
b.(18 X 125) - (18 X 25)
a.(128 x 9)-(28 x 9)
b.(38 x 16) + (62 x 16)
a.(87 x 12)+(87 x 5)-(87 x 4)

3+x

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

you can not solvr this without numbers

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
