Answer: w=5 , L= 2+2(5)=12

Step-by-step explanation:

L=2+2W

A= 60

LxW=60, now we will replace the L

(2+2W)(W)=60   we multiply

2w^2+2w=60

2w^2+2w-60=0  we divide by 2 the equation so we can work easier

w^2+w-30=0

find out w using the quadratic equation

we will get 2 solution,

w=5 and another solution is -6, which is not valid, as the side can not be negative

Answer:

18x-16

Step-by-step explanation:

expression: (11x-8)+7(x-1)

ok so what you want to do is combine like terms

but first you are going to distribute

(11x-8)+(7x-8) you distribute the 7

they you can subtract 8 from -8 and that will give you -16

you will then add 11x and 7x which will get you 18x

the final expression will be 18x-16

Answer:

X=5

Step-by-step explanation:

(step 1) 2 - 3x = -x - 8

-3x + 2 = -x -8

(step 2)

-3x + 2 = -x - 8

-3 + 2 - 2 = -x -8 -2

(step 3)

-3x =  -x- 10

(step 4)

-3 + x = -x -10 +x

(step 5)

-2x = -10

Based on the information presented, it can be inferred that Mia made 8 baskets last Saturday.

To calculate the number of baskets Mia made last Saturday we must take into account the following information:

To calculate the number of baskets Mia made, we must divide 24 by 3 to find the number of baskets she made last Saturday.

So, it can be inferred that Mia made 8 baskets last Saturday.

Answer in screenshot.

When x = 6 and y = 9, the value of the expression (x + y)² is 225.

Given an expression:

(x + y)²

It is required to find the value of the expression when the value of x = 6 and the value of y = 9.

In order to find the required value of the expression when x = 6 and y = 9, it is required to substitute the value of x and y accordingly to the given expression.

So, substitute x = 6 and y = 9 in the expression (x + y)².

Then the expression becomes:

(x + y)² = (6 + 9)²

           = 15²

            = 225

Hence the value is 225.

Answer:

3x³ - 8x² - 7x + 12

Step-by-step explanation:

We multiply these terms, (so expand the brackets). Referring to the diagram attached, we multiply the first terms, outer terms, inner terms, and last terms.

Let's first look at the first two (we will do something about the third brackets later):

(3x+4)(x-1)

Firsts:

3x²

Outer:

-3x

Inner:

4x

Last:

-4

Now we combine:

3x² - 3x + 4x - 4

= 3x² + x - 4

So from the whole equation, we now have this:

(3x² + x - 4)(x - 3)

We do a similar thing here.

3x³ - 9x² + x² - 3x - 4x + 12

Simplify:

3x³ - 8x² - 7x + 12

Only quadratic function will follow the rule because it has even degree polynomial. Thus option D) Quadratic is correct.

Function is a type of relation, or rule, that maps one input to specific single output.

Given information;

A function is graphed on a coordinate grid.

As the domain values approach infinity, the range values approach infinity.

      Domain: If x tends to infinity then

      Range: y tends to infinity

As the domain values negative infinity, the range values approach infinity;

      Domain: If x tends to negative infinity  then

      Range: y tends to infinity

Thus, Only quadratic function will follow the rule because it has even degree polynomial

Quadratic function: ax² + bx + c = 0

Degree = 2 and leading coefficient is positive.

Domain: [tex]x (- \infty, \infty)[/tex]

Range: [tex]y ( b, \infty)[/tex]

Answer:

There were 8 more silver coins than gold coins in the jar.

Step-by-step explanation:

Given that:

Total coins in the jar = 80 coins

Gold coins = 25% of total coins

Number of gold coins = [tex]\frac{25}{100}*80[/tex]

Number of gold coins = 20

Silver coins = 35% of total

Number of silver coins = [tex]\frac{35}{100}*80[/tex]

Number of silver coins = 28

Copper coins = 40% of total

Number of copper coins = [tex]\frac{40}{100}*80=32[/tex]

Difference between silver and gold coins = No. of silver coins - No. of gold coins

Difference = 28-20 = 8

Hence,

There were 8 more silver coins than gold coins in the jar.

Answer:

The standard form of this hyperbola is [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex].

Step-by-step explanation:

From Analytical Geometry, the standard form of the hyperbola is defined by the following expression:

[tex]\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}} = 1[/tex] (1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]a, b[/tex] - Semiaxis lengths, dimensionless.

[tex]h, k[/tex] - Coordinates of the center, dimensionless.

Let the hyperbola be defined by [tex]9\cdot x^{2}-5\cdot y^{2}-54\cdot x -10\cdot y +31=0[/tex], we proceed to derive the standard form by algebraic means:

1)  [tex]9\cdot x^{2}-5\cdot y^{2}-54\cdot x -10\cdot y +31=0[/tex] Given

2) [tex](9\cdot x^{2}-54\cdot x)+(-1) \cdot (5\cdot y^{2}+10\cdot y)+31 = 0[/tex] Commutative and associative properties/[tex](-1)\cdot a = -a[/tex]

3) [tex](9\cdot x^{2}-54\cdot x + 81)+(-81)+(-1)\cdot (5\cdot y^{2}+10\cdot y +5)+(-1)\cdot (-5)+31 = 0[/tex] Modulative, distributive and associative properties/[tex](-1)\cdot a = -a[/tex]/Existence of the additive inverse

4) [tex](3\cdot x-9)^{2}+(-1)\cdot (\sqrt{5}\cdot y +\sqrt{5})^{2}+(-81)+5+31 = 0[/tex] Perfect trinomial square/[tex](-a)\cdot (-b) = a\cdot b[/tex]/Commutative property

5) [tex]9\cdot (x-3)^{2}+(-1)\cdot (5) \cdot (y+1)^{2}-45 = 0[/tex] Distributive property/[tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]/Definition of addition and subtraction.

6) [tex]9\cdot (x-3)^{2}-5\cdot (y+1)^{2}= 45[/tex]    [tex](-1)\cdot a = -a[/tex]/Compatibility with addition/Existence of additive inverse/Modulative property.

7)  [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex] Compatibility with multiplication/Definition of division/Distributive property/Result.

The standard form of this hyperbola is [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex].

Answer:
