An artist prints T-shirts to sell at a fair for $14 each. The artist has some initial T-shirts ready to sell and works for h hours more, printing a constant number of T-shirts every hour. The expression 14(12h+30) represents the amount, in dollars, the artist will earn selling all the T-shirts. Part B Which statement about (12h+30) is true? The value 12 is a coefficient, and the value 30 is a constant in the expression (12h+30). The value 12 is a coefficient, and the value 30 is a constant in the expression ( 12 h + 30 ) . The value 12 is a constant, and the value 30 is a coefficient in the expression (12h+30). The value 12 is a constant, and the value 30 is a coefficient in the expression ( 12 h + 30 ) . The values 12 and 30 are both coefficients in the expression (12h+30). The values 12 and 30 are both coefficients in the expression ( 12 h + 30 ) . The values 12 and 30 are both constants in the expression (12h+30). The values 12 and 30 are both constants in the expression ( 12 h + 30 ) .

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
