Answer:

11 + x

Step-by-step explanation:

A = LW

W = $\frac{A}{L}$

Plug in given information:

W = $\frac{121-x^{2} }{11-x}$

Factor the numerator:

W = $\frac{(11+x)(11-x)}{(11-x)}$

Cancel (11 - x):

W = 11 + x

Answer:

$\text{The width of rectangle}=9x\text{ meters}$

Step-by-step explanation:

We have been given that the rectangle has an area of $18x^3$ square meters and a length of $2x^{2}$ . We are asked to find the width of rectangle.

Since we know that area of a rectangle is width times length of the rectangle, so we can find width of our given rectangle by dividing given area by length of rectangle.

$\text{Area of rectangle}=\text{Width of rectangle *Length of the rectangle}$

$\frac{\text{Area of rectangle}}{\text{Length of rectangle}}=\frac{\text{Width of rectangle *Length of the rectangle}}{\text{Legth of rectangle}}$

$\text{The width of rectangle}=\frac{\text{Area of rectangle}}{\text{Length of rectangle}}$

Upon substituting our given values in above formula we will get,

$\text{The width of rectangle}=\frac{18x^3\text{ meter}^2}{2x^2\text{ meters}}$

$\text{The width of rectangle}=\frac{9x^3\text{ meters}}{x^2}$

Using exponent rule for quotient $\frac{a^m}{a^n}=a^{m-n}$ we will get,

$\text{The width of rectangle}=9x^{3-2}\text{ meters}$

$\text{The width of rectangle}=9x^{1}\text{ meters}=9x\text{ meters}$

Therefore, width of our given rectangle will be 9x meters.

Answer:

P(B and D) = 0.35

Step-by-step explanation:

It is a probability tree diagram. Here to find P(B and D):

apply method:

P(A and B) = P(A) × P(B)

Here given:

P(B) = .5

P(D) = .7

So, P(B and D):

P(B) × P(D)

.5 × .7

.35 ≈ 0.35
