Find the value of x.
lawyer [7]

Answer:

\huge\boxed{x=\sqrt{70}}

Step-by-step explanation:

ΔABC and ΔADB are similar (AAA).

Therefore the corresponging sides are in proportion:

\dfrac{AB}{AD}=\dfrac{AC}{AB}

Substitute:

AB=x\\AC=7+3=10\\AD=7

\dfrac{x}{7}=\dfrac{10}{x}       <em>cross multiply</em>

(x)(x)=(7)(10)\\\\x^2=70\to x=\sqrt{70}

The volume of a rectangular prism is (x^3 – 3x^2 + 5x – 3), and the area of its base is (x^2 – 2). If the volume of a rectangula
bixtya [17]

Answer:

The height of the prism is equal to h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)

Step-by-step explanation:

we know that

The volume of a rectangular prism  is equal to

V=Bh

where

B is the area of the base of the prism

h is the height of the prism

In this problem we have

V=x^{3}-3x^{2}+5x-3

B=x^{2}-2

substitute in the formula and solve for h

x^{3}-3x^{2}+5x-3=(x^{2}-2)h

h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)
