The answer is 8x-1 I believe
I believe the answer is A. Because x could equal the number of shirts on 3 tables, so 3x and then 9 even stacks would make sense. I hope that helps :)
ANSWER
The is 10 is meters
EXPLANATION
The area of a tra-pezoid can be calculated using the formula;
We substitute the values to get,
The height is 10 meters.
Answer:
--------------------------------
Given lines:
- 3x + y = 1 and y + 6 = - 3x
Convert both equations to slope-intercept form of y = mx + b:
- 3x + y = 1 ⇒ y = - 3x + 1
- y + 6 = - 3x ⇒ y = - 3x - 6
Slopes are same, so these are parallel lines, and the distance between parallel lines is:
- , where b₁, b₂ - y-intercepts, m- slope
Substitute and calculate:
Answer:
A) x² + 7x - 9
