The solution to the problem and how would I work it out?
Zinaida [17]

Answer:

x >=5  or x <=-3

Step-by-step explanation:

Solve an absolute value inequality

3|x-1| >= 12

Divide each side by 3

3/3|x-1| >= 12/3

|x-1| >= 4

Now there are two solutions

x-1 >= 4   or x-1 <= -4

Add 1 to each side

x-1+1 >= 4+1   or  x-1+1 <= -4+1

x >=5  or x <=-3

What is the area of the figure below?<br><br> A. 31.5 m<br> B. 63 m<br> C. 84 m<br> D. 126 m
lapo4ka [179]
Hi! For the area of a parallelogram, we just need to multiply the base and the height. It may sound simple but the tricky part in this problem is determining which one is the height.

For a parallelogram, the height is defined as the measurement PERPENDICULAR to the base. Therefore, for this problem, we need to multiply 14 and 4.5 instead of 14 and 6.

14*4.5=63

ANSWER: B. 63 square meters.
