A=2b^3-1 what's the value of b if a is 13

skelet666 [1.2K]

$\sf~A=2b^3-1$

Plug in A = 13

$\sf~13=2b^3-1$

Add 1 to both sides:

$\sf~14=2b^3$

Divide 2 to both sides:

$\sf~7=b^3$

Find the cube root of both sides:

$\sf~b=\sqrt[3]{7}$

$\sf~b\approx~1.91$

oee [108]

$\triangle BCA\ \text{and}\ \triangle DCB\ \text{are similar (AAA). Therefore the sides are in proportion:}\\\\\dfrac{BC}{CD}=\dfrac{AC}{BC}\\\\\text{We have}\\\\BC=m\\CD=7\\AC=7+11=18\\\\\text{Substitute:}\\\\\dfrac{m}{7}=\dfrac{18}{m}\qquad\text{cross multiply}\\\\m^2=(7)(18)\\\\m^2=126\to\boxed{m=\sqrt{126}}\to\boxed{A.}$
