Which sum or difference is modeled by the algebra tiles?

option 4

Step-by-step explanation:

(2x - 3) - (-3x + 4)

= 2x - 3  +3x  - 4    {remove parenthesis by bringing in th (-) sign}

= 2x + 3x - 3 - 4   {add the like term}

= 5x - 7

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

c
