Estaban wants marble bookends cut at a 60° angle, as shown. If Estaban wants his bookends to be between 7.5in and 8in. Tall, what length d should the marble cutter make the base of the book ends? Explain.

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

just get this app called photo math it should be able to do those

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
