4x^3+6x^2-9x+1 is an example
2 a + b = 15.7
Since the sides are equal length, the equation is:
2 · 6.3 + b = 15.7
We can solve it:
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
2 is the GCF of <span>2+18+40
.</span>
90x = 12
Divide both sides by 90
x = 0.1333....
Move the decimal to places to the right.
13.333% repeating.
Answer:
the answer is B.
Step-by-step explanation:
100*20 + 1/2*(60-20)*(100 - 12)
=2000 + 1/2*40*88
=3760
