First add like terms in this case 1+7=8. Then then divide. 2x/8= 4. X=4
Answer:
BC = 144 units
Step-by-step explanation:
BC = BD + DC , substitute values
8x = 4x + 10 + 3x + 8 = 7x + 18 ( subtract 7x from both sides )
x = 18
Thus
BC = 8x = 8 × 18 = 144 units
Plug in your numbers so the equation will turn out to be 3(4)+6/2(3) , you need to simplify 6/2 which will be 3 and 3 times 3 = 9 so the equation will be 3(4)+9 and 3 times 4 = 12 so the equation will now be 12+9 = 21
Answer= 21
<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>
If you reduce 50:125 it will be 2:5.
