<span>4(x2 – 2) = 28
4x^2-8=28 Distributive law of multiplication
4x^2+8=28+8 Additive identity
4x^2=36 ; adding 8 to both sides
x^2 =9, dividing both sides by 4
x= +/- 3</span>
W represents the weight of each book
2w + 4 = 18
2w = 18 - 4
2w = 14
w = 14/2
w = 7 oz <===
Answer:
Left skewed
Step-by-step explanation:
Looking at the box and whisker plot attached showing the wait times and the number of times they occur, we can see that as we approach the left, the number of times the wait time occurs increases. The box plot also shows like as if the box was pushed to the right as the center line is closer to the right than left.
Thus, we can say it's left skewed.
Answer:
8 ≥ x+3 or x ≥ 12
Step-by-step explanation:
The sum of a number (additon) and 3 (x+3) is no more than (so less than or equal to eight) OR is more than 12 ( x is more than 12, x ≥ 12 )
Subtract 3 from both sides
x>-1 is the answer
