a fence along a rectangular yard has a total length of (15x^2-7x+3) feet. (5x^2+4) feet represents the part of the fence that needs to be repaired. write the polynomial that represents the part of the fence that does not need repairing

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

its totaly b

your welcome btw

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft

$25 becasue a 10 increase would make it from 80 to 50
