Step-by-step explanation:

x= -3, -7

Answer:

x = -7, -3

Step-by-step explanation:

Try to factor the left side of the equation.  

(x +7)(x + 3) = 0    Remember that if AB = 0, then A = 0 or B = 0 or both  A and B = 0

Therefore,  x + 7 = 0  or x + 3 = 0

                        x = -7  or x = -3

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Length : Breadth : height = 3 : 4 : 6

Length = 3x

Breadth = 4x

Height = 6x

Volume of cuboid = 576 sq.cm

length * breadth * height = 576

3x * 4x * 6x = 576

       72x³   = 576

             x³ = 576/72

            x³ =   8

            x³ = 2³

x = 2

Length = 3*2 = 6 cm

Breadth = 4* 2 = 8 cm

Height = 6*2 = 12 cm

Total surface area = 2*(lb + bh + hl)

                             = 2 * (6*8 + 8*12 + 12*6)

                            = 2 * (48 + 96 + 72)

                            = 2 * 216

                            = 432 sq.cm

Step-by-step explanation:

The value of 23 % of 42 is 9.7

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be A = 42

Now , let the percentage of the number A = 23 %

And , the equation will be

The 23 % of the number be = y

So , y = 23 % of 42

And , the equation is

y = ( 23 / 100 ) x 42

y = 0.23 x 42

On simplifying the equation , we get

y = 9.66

y ≈ 9.7

Therefore, the value of y is 9.7

Hence , The value of 23 % of 42 is 9.7

Step-by-step explanation:

Complete question

Emma receives a large box in the mail. The box is 10cm longer than it wide, and the height is 6 cm more than the width. Find the polynomial function for volume of the box

Let the length be x

Let the width be y

let the height be z

If the box is 10cm longer than it wide, then x = y + 10

Also if the height is 6 cm more than the width,

z = y + 6

Volume of the box = xyz

Substitute

Volume of the box = (y+10)(y)(y+6)

Volume of the box = (y+10)(y²+6y)

Volume of the box = y³+6y²+10y²+60y

Volume of the box =  y³+16y²+60y

Hence the required polynomial function is y³+16y²+60y

The value of the function at x = -3 is -1

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.

Given that a graph of y= f(x), we need to find f(-3)

The graph tells the value of y when x = -3 is -1

Hence, The value of the function at x = -3 is -1

Answer:

x = 80

Step-by-step explanation:

(6/12)*x-10 = 30 // - 30

(6/12)*x-30-10 = 0

1/2*x-40 = 0 // + 40

1/2*x = 40 // : 1/2

x = 40/1/2

x = 80

Hi there!

x=80

1.Multiply the terms:

[tex]\frac{6}{12}[/tex]·[tex]80=\frac{480}{12}[/tex]

2.Divide the fraction term:

[tex]\frac{480}{12}=40[/tex]

3.Subtract the two terms:

Answer:

3 gallons

Step-by-step explanation:

Length of the rectangular wall = 23.6 feet

Width of the rectangular wall = 19.2 feet

Surface area of the wall = 23.6 × 19.2

                                        = 453.12 square feet

∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon

∴ 1 square feet of the wall will be covered by the amount of paint = [tex]\frac{1}{200}[/tex] gallons

∴ 453.12 square feet will require the amount of paint = [tex]\frac{453.12}{200}[/tex]

                                                                                         = 2.2656 gallons

Therefore, minimum 3 gallons will be required to paint the wall.

m=(y2-y1)/(x2-x1)

m=(4-7)/(8-5)

m=-3/3

m=-1

Answer:

m = -1

Step-by-step explanation:

m represents the slope.

Answer:

3 or 3/1

Step-by-step explanation

the equation for finding the slope when given two coordinate pairs is (y₂ - y₁)/(x₂ - x₁), aka change in y over change in x.

pick one of your coordinate pairs to be y₂ and x₂. it doesn't matter which coordinate pair you choose. the remaining coordinate pair will be your y₁ and x₁.

for this example, i'll use the coordinate pair (7, 2) as my y₂ and x₂ and (1, 4) as my y₁ and x₁.

first, substitute the x-value and y-value from the first coordinate pair.

(y₂ - y₁)/(x₂ - x₁) ⇒ (7 - y₁)/(2 - x₂)

then substitute the y-value and x-value from the remaining coordinate pair.

(7 - y₁)/(2 - x₂) ⇒ (7 - 4)/(2 - 1)

subtract 7 - 4.

(7 - 4)/(2 - 1) ⇒ (3)/(2 - 1)

subtract 2 - 1.

(3)/(2 - 1) ⇒ (3)/(1) or 3/1

simplify.

3/1 ⇒ 3

i hope this helps! have a great day <3
