A triangular sign is being made. • The area is to be no greater than 300 square feet.
• The height of the triangle is to be 3 times x, the length of the base.
Which inequality can be used to determine the possible lengths of the base, where x is a nonnegative real number?
O A. 3x2 > 300
OB. 3x2 < 300
O c. x2 300
D. x2 < 300

The answer is C

Step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

72 is the answer to this problem
