The width and the length of the rectangle are equal to 6√5 units and 3√5 units, respectively.

<h3>What are the dimensions of the rectangle?</h3>

In this problem we find the area of the rectangle and the ratio of the length to the width of the figure. Mathematically speaking, the area of the rectangle is described by the following formula:

A = (2 · x) · x

A = 2 · x²

If the area of the rectangle is equal to 90 square units, then the width of the rectangle is:

2 · x² = 90

x² = 45

x² = 3² × 5

x = 3√5

The width of the rectangle is equal to 3√5 units. By the given ratio, the length of the rectangle is equal to 6√5 units.

Therefore, the length and width of the rectangle are equal to 6√5 units and 3√5 units, respectively.

<h3>Remark</h3>

The lower part of the picture is not related to the statement.

Write as an expression and simplify
Alexus [3.1K]

Answer:

Part a) (2m+7n)(2m-7n)

Part b) x^2-16xy+64y^2

Part c) 216a^3b^6

Part d)  (a^2-b^2)

Step-by-step explanation:

Part a) The difference of the squares of 2m and 7n.

we know that

The difference of the squares formula is equal to

(a^2-b^2)=(a+b)(a-b)

substitute

(2m)^2-(7n)^2=(2m+7n)(2m-7n)

Part b) The square of the difference of x and 8y

The formula of the square of the difference between two numbers is equal to

(a-b)^2=a^2-2ab+b^2

substitute

(x-8y)^2=x^2-2(x)(8y)+(8y)^2=x^2-16xy+64y^2

Part c) The tripled product of 6a and b^2

we have

(6ab^{2})(6ab^{2})(6ab^{2})=(6ab^{2})^3=(6^3)(a^3)(b^{2})^3=216a^3b^6

Part d) The product of the sum of a and b and their difference

The expression is equal to

(a+b)(a-b)

The expression represent the difference of the squares between a and b

so

(a+b)(a-b)=(a^2-b^2)

40 points | Sierra and Alek each have five cousins. Their ages are listed below.
faust18 [17]

Find the mean for both:

Sierra: 2 + 11 + 12 + 13 + 15 =  53

53/5 =10.6

Median is the middle value = 12

Alek: 9 + 11 + 11 + 12 + 13 = 56

56/5 = 11.2

Median = 11

A: The medians do not equal the mean.

B: Sierra's are more spread out, ( no identical ages and a greater range ).

C: Sierra's mean is less than Alek.

D. Sierra has an outlier (2).

The answer would be B
