Answer:

Width = 7 feets ; length = 16 feets

Step-by-step explanation:

Given the following :

Area of meadow = 112 sq feet

Width = W (smaller dimension and 2 sides)

Length = L (longer dimension and 1 side)

Yards of fence = 30 feets ;

Hence,

L + W = 30

L + 2W = 30

L = 30 - 2W - - - (1)

Recall:

Area = L * W = 112

Substitute value of L

112 = (30 - 2W) * W

112 = 30W - 2W²

2W² - 30W + 112 = 0

W² - 15W + 56 = 0

W² - 8W - 7W + 56 = 0

W(W - 8) - 7(W - 8) = 0

(W - 8) = 0 or (W - 7) =0

W = 8 or W = 7

Since length should be as long as possible, we take the shorter width :

W = 7

L + 2W = 30

L = 30 - 14

L = 16 feets

Answer:  [tex]x^2+y^2=\dfrac{105\pm 18\sqrt6}{2}[/tex]

Step-by-step explanation:

EQ1:  x + y = 12     --> x = 12 - y

EQ2:  xy = 15      

Substitute x = 12-y into EQ2 to solve for y:

(12 - y)y = 15

12y - y² = 15

0 = y² - 12y + 15

    ↓     ↓         ↓

  a=1   b= -12   c=15

[tex].\ y=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\.\quad =\dfrac{-(-12)\pm \sqrt{(-12)^2-4(1)(15)}}{2(1)}\\\\\\.\quad =\dfrac{12\pm \sqrt{144-120}}{2}\\\\\\.\quad =\dfrac{12\pm \sqrt{24}}{2}\\\\\\.\quad =\dfrac{12\pm 2\sqrt{6}}{2}\\\\\\.\quad =6\pm \sqrt{6}[/tex]

Now, let's solve for x:

[tex]xy=15\\\\x(6\pm\sqrt6)=15\\\\x=\dfrac{15}{6\pm\sqrt6}\\\\\\x=\dfrac{15}{6\pm\sqrt6}\bigg(\dfrac{6\pm\sqrt6}{6\pm\sqrt6}\bigg)=\dfrac{6\pm \sqrt6}{2}[/tex]

Lastly, find x² + y² :

[tex]y^2=(6\pm \sqrt6)^2\quad \rightarrow \quad y^2=36\pm 12\sqrt6 +6\quad \rightarrow \quad y^2=42\pm 12\sqrt6[/tex]

[tex]x^2=\bigg(\dfrac{6\pm \sqrt6}{2}\bigg)^2\quad \rightarrow \quad x^2=\dfrac{42\pm 12\sqrt6}{4}\quad \rightarrow \quad x^2=\dfrac{21\pm 6\sqrt6}{2}[/tex]

[tex]x^2+y^2=\dfrac{21\pm 6\sqrt6}{2}+42\pm 12\sqrt6\\\\\\.\qquad \quad = \dfrac{21\pm 6\sqrt6}{2}+\dfrac{84\pm 24\sqrt6}{2}\\\\\\. \qquad \quad = \dfrac{105\pm 18\sqrt6}{2}[/tex]

Answer:5 with an exponent of 3•55• 53

Step-by-step explanation:

Just make the equation smaller looking by putting together numbers that can be turned into one like there was 4, 5’s so turn it into 5 with and exponent of 3

The value of the expression 5⁷ / 5² will be  5×5×5×5×5. which is the correct answer would be an option (C).

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable

The expression is given below.

⇒ 5⁷ / 5²

⇒ 5⁷⁻²

⇒ 5⁵

⇒ 5×5×5×5×5

Hence, the value of the expression 5⁷ / 5² will be 5×5×5×5×5. which is the correct answer would be an option (C).

The side length of a square game board with an area of 199 inches² is 14.11 inches.

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely cover the surface of a closed figure.

Given:

The area of the square is 199 inches²

Calculate the length of the square as shown below,

Area of the square = The length of the square ×  The length of the square

199 = l²   (Here l is the length of the square)

l = √199

l = 14.11 inches

Thus, the length of the board is 14.11 inches.

Answer: B.1/24

Step-by-step explanation:

Find out the number of people in spin class and those lifting weights, subtract them from the total number in the gym and then make this a fraction.

Step 1

Number of people in spin class ;

= 5/8 * 48

= 30 people

Number of people lifting weights;

= 1/3 * 48

= 16 people

Step 2

Number of people running

= 48 - 30 - 16

= 2 people

Step 3

Convert this to a fraction in its lowest form;

= 2/48

= 1/24

Answer:

Step-by-step explanation:

It will be easier if you bring that binomial in-front, imo. But the main thing you want to do here is actually really easy. You have to distribute that x to every single term in the trinomial, then do the same thing for the 5. Add up everything.

Distribute the x and 5 like this:

[tex]x(2x^2+7x-10) + 5(2x^2+7x-10)[/tex]

[tex]2x^3+7x^2-10x+10x^2+35x-50[/tex]

Now combine like terms:

[tex]2x^3+17x^2+25x-50[/tex]

There's your answer. Btw, standard form means the exponents are in order high to low and all variables before constants

The product of the expression is 2x³ + 17x² + 25x - 50.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2x² + 7x - 10 and x + 5

Multiply both expressions.

(2x² + 7x - 10) x (x + 5)

2x³ + 10x² + 7x² + 35x - 10x - 50

Combine like terms.

2x³ + 17x² + 25x - 50

Thus,

The expression is 2x³ + 17x² + 25x - 50.
