Ryan is making a small sign in the shape of a triangle for her store. He wants the height of the triangle to be 8 inches. The area of the sign must be more than 20 square inches. (The sign has to be seen from the
sidewalk.) Write an inequality that describes the possible base lengths (in inches) of the triangle.
Use b for the base length of the triangular sign.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

answer: b f g .

step-by-step explanation:

its kinda hard to answer this when we dont have all the information that we need.
