<span>A length is constructible if it can be obtained from a nite number of applications of a compass and straightedge. A constructible number is a constructible length or the negative of a constructible length. The demonstrations in this section, elsewhere in the text, and in class emphasize three part of the problem solving process for constructions:
1. Investigation or analysis. The usual approach is to imagine the problem is solved and search for relationships or properties that will allow us to accomplish the construction.
2. Construction. We propose the steps in the construction and perform the construction.
3. Proof: We justify that the constructions steps are valid and that the construction accomplishes what it was supposed to do.</span>
Answer:
The fourth term is -18
Step-by-step explanation:
an = -2(an-1) +10
This is the recursive formula
a1 = 6
a2 = -2(a1) +10 = -2(6) +10 = -12+10 = -2
a3 = -2(a2) +10 = -2(-2) +10 = 4+10 = 14
a4 = -2(a3) +10 = -2(14) +10 = -28+10 = -18

x=-3,5
Answer:
6 centimeters and 4 centimeters
Step-by-step explanation:
According to the Triangle Inequality, the sum of the lengths of any two sides of a triangle has to be greater than the third side. The answer choices that satisfy the Triangle Inequality is 6 centimeters and 4 centimeters.
