Answer: 4(x - 1)(x^2 + x + 1)</h3>
==================================================
Work Shown:
4x^3 - 4
4(x^3 - 1)
4(x - 1)(x^2 + x + 1)
In the last step, I used the difference of cubes factoring formula which is
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
If you are setting it up as a proportion then you would muiltiply the 12 and x to get 12x. Then muiltiply the 80 and 1 to get 80. So 12x=80. Divide the 12 to get your final answer
Answer:
x = 2
Step-by-step explanation:
BO = OD
they are apart of the same line segment with O as the midpoint of BD
since they're equal set equal and solve for x
7x + 4 = 18 subtract 4 from both sides
7x = 14 divide both sides by 7
x = 2
