Double check some of my work ?

1. 2(3) - 3(-2) = 0?

2. the piggy bank contained $25, and $1.50 is added each day. would the expression of this be written as 25 + (1.50x)?

3. in the first set, the volleyball team made only 8 shots worth one point each. would the expression for this just be 1 times 8?

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
