Answer:

Step-by-step explanation:

Δ ABE and Δ DCE are similar, thus the ratios of corresponding sides are equal, that is

$\frac{BE}{CE}$ = $\frac{AE}{DE}$ , substituting values gives

$\frac{BE}{3}$ = $\frac{5}{2}$ ( cross- multiply )

2BE = 15 ( divide both sides by 2 )

BE = 7.5 → A

Which ecpression is equivalent to sqrt 8x^7y^8?

mars1129 [50]

$Domain:\ x\geq0\ \wedge\ y\in\mathbb{R}$

$\sqrt{8x^7y^8}=\sqrt8\cdot\sqrt{x^7}\cdot\sqrt{y^8}=\sqrt{4\cdot2}\cdot\sqrt{x^6\cdot x}\cdot\sqrt{y^{4\cdot2}}\\\\=\sqrt4\cdot\sqrt2\cdot\sqrt{x^6}\cdot\sqrt{x}\cdot\sqrt{(y^4)^2}=2\sqrt2\cdot\sqrt{x^{3\cdot2}}\cdot\sqrt{x}\cdot y^4\\\\=2y^4\sqrt2\cdot\sqrt{(x^3)^2}\cdot\sqrt{x}=2y^4\sqrt{2x}\cdot x^3\\\\=\boxed{2x^3y^4\sqrt{2x}}$
