Answer:

width = 6 ft

length = 21 ft

Step-by-step explanation:

Forming algebraic expressions and finding the dimensions of a rectangle:

 Width = w ft

 length =  3*w + 3 = (3w + 3) ft

              2l +2w = P

 2(3w + 3) + 2w = 54

Use distributive property to open the brackets,

 2*3w + 2*3 + 2w = 54

        6w + 6 + 2w = 54

Combine like terms,

          6w + 2w + 6 = 54

               8w   + 6   = 54

Subtract 6 from both sides,

                      8w    = 54 - 6

                         8w = 48

Divide both sides by 8

                           w = 48 ÷ 8

                           [tex]\sf \boxed{\bf w = 6 \ ft}[/tex]

l = 3w + 3

 = 3*6 + 3

 = 18 + 3

l = 21 ft

58, 62 and 74 are the numbers between 50 and 80 that has exactly 4 factors with 2 being one of them 4.

As per the question statement, we are required to find out the numbers between 50 and 80 that has exactly 4 factors with 2 being one of the factors.

To solve this question, we need to know that every or any number in the number system as has at least 2 factors: 1 and the number itself.

Since we are to find numbers with exactly 4 factors, 2 being one of the factors and as per the above mentioned concept, two of the remaining three factors will be 1 and the number itself, the fourth factor has to be a prime number as prime numbers have no other factors than 1 and itself.

That is, we will have to find prime numbers (say "n") which when multiplied by 2 lies within the range of 50 and 80,

[tex]or, 50\leq (n*2) \leq 80\\or, \frac{50}{2}\leq n\leq \frac{80}{2}\\ or, 25\leq n\leq 40[/tex]

That is, we will need to find the prime numbers between 25 and 40; They are 29, 31 and 37.

Hence, our required numbers are [(29 * 2) = 58], [(31 * 2) = 62] and

[(37 * 2) = 74]. They lie between 50 and 80 that has exactly 4 factors with 2 being one of them.

The value of d is 18.

Given, the slope of the line is 3.

Slope equals a height change (Change in width) You may also say that a slope is a climb or a run. This formula changes if the graph's horizontal axis is represented by x and the vertical axis by y: Slope is equal to (y-change)/ (Change in x)

Two points which lie are N(₋2 , 3) and D(3,d)

slope of the line = y₂ ₋ y₁/x₂ ₋ x₁

let the points N(₋2 , 3) be (x₁ , y₁)

and D(3,d) be (x₂ , y₂)

therefore, 3 = d ₋ 3/3 ₋ (₋2)

3 = d ₋ 3/3 ₊ 2

3 = d ₋ 3 / 5

15 = d ₋ 3

d = 15₊3

d = 18

Hence we get the value of d as 18.

Answer:

1.3 is the correct answer

Step-by-step explanation:

Using exponent properties, the equivalent expression is given as follows:

[tex]\left(\frac{2}{3}\right)^14[/tex]

Two thirds to the fourth power is given by:

[tex]\left(\frac{2}{3}\right)^4[/tex]

Two thirds to the third power is given by:

[tex]\left(\frac{2}{3}\right)^3[/tex]

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:

[tex]\left(\frac{2}{3}\right)^4 \times \left(\frac{2}{3}\right)^3 \left(\frac{2}{3}\right)^{4 + 3} = \left(\frac{2}{3}\right)^7[/tex]

Then, this entire expression is raised to the second power, meaning that:

[tex]\left[\left(\frac{2}{3}\right)^7\right]^2 = \left(\frac{2}{3}\right)^7 \times \left(\frac{2}{3}\right)^7 = \left(\frac{2}{3}\right)^{7+7} = \left(\frac{2}{3}\right)^14[/tex]

The function f ( x ) = 2 x² + 5 will have the value 23 for f (- 3).

We are given the function:

f ( x ) = 2 x² + 5

We need to find the value of f ( -3 ).

We will do this by substituting the value of x = - 3 in the function and then evaluating the expression.

Putting x = -3 in the function, we get that:

f ( x = - 3 ) = 2 (- 3)² + 5

Solving the square, we get that:

f (- 3) = 2 ( 9 ) + 5

Simplifying the expression, we get that:

f (- 3) = 18 + 5

f (- 3) = 23
