solve the equation:
-4(m + 6) = -8

Answer:

C. Multiply 1st equation by 3, then add together

Step-by-step explanation:

X+y=10

3(x+y)=3(10)multiply by 3

3x+3y=30 add to following equation

2x-3y=6

5x=36

Answer:

Step-by-step explanation:

y=x^2-8x+14

To write in vertex form, group the two x-terms to make a complete square, adjust the constant term accordingly

y = x^2-8x+16  -2

factor the first three terms on the right hand side

y = (x-4)^2 -2

This means that the vertex is at x-4 = 0, or x=4, and y=2.

Answer:

336 cm²

Step-by-step explanation:

rectangle area:

b×h = 24×7,5=180 cm²

" " = 6,5×24=156 cm²

total area: 180+156=336 cm²

Answer:

3 * (½*2*5) = x

Step-by-step explanation:

Cost of carpeting = $3 per square foot

We have a triangular section to cover having the following dimensions:

base = 2 yd

height = 5 yd

First, let's find the area of the section = area of triangle

Area of triangle = ½*base*height

Area of the triangular section of the floor = ½*2*5

If $3 will cover 1 ft², therefore,

x will cover ½*2*5

Thus:

3 * (½*2*5) = x

Answer:

Hi! The answer to your question is the range is 23

Step-by-step explanation:

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 62-39=23

VOCAB:

Minumum Data = Smallest Number

Maximum Data = Largest Number

Data Range = The set of y-values that a function passes through, Also the right coordinate in a coordinate pair.

In statistics, the difference between the largest number and the smallest numbers in a data set.

The statement about rectangles and rhombuses that is always true is that both figures are quadrilaterals.

A quadrilateral is a closed, two-dimensional shape which has four straight sides.

In other word, a quadrilateral is a plane figure that has four sides or edges, and also has four corners or vertices.

Quadrilateral has four sides.

Rhombuses and rectangles have four sides. Therefore, they are both quadrilaterals.

Answer:

volume of square based prism = a²h

therefore

150 in³ = x²y

y = 1.5x

150 = 1.5x³

100 = x³

x = ³√100 ≈ 4.64 in

y = 1.5x ≈ 6.96 in

Answer:

The probability that all 4 units are good is 10.66%.

Step-by-step explanation:

Given that a shipement of 14 microwave ovens contains six defective units, and a vending company has ordered 4 of these units and selection will be random, to determine what is the probability that all 4 units are good the following calculation must be performed:

14 - 6 = 8

8/14 x 8/14 x 8/14 x 8/14 = X

0.5714 x 0.5714 x 0.5714 x 0.5714 = X

0.1066 = X

0.1066 x 100 = 10.66

Therefore, the probability that all 4 units are good is 10.66%.

Answer:

4

Step-by-step explanation:

The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.

Example, the degree of 4x^8 is 8.

So the degree of 5x^4 is 4.

The degree of 3x^2 is 2.

The degree of 1 is 0 since there is no variable in this expression.

So the degree of 5 x^4 + 3 x^2 + 1 is 4.

Answer: [tex]254.94\ ft[/tex]

Step-by-step explanation:

Given

Building A is 490 feet tall and building B is 754 ft tall.

If the angle of depression from building B to the top of building A is [tex]46^{\circ}[/tex]

Difference in the height of the two buildings is [tex]754-490=264\ ft[/tex]

If the difference between them is [tex]x[/tex]

From the figure, we can write

[tex]\Rightarrow \tan 46^{\circ}=\dfrac{264}{x}\\\\\Rightarrow x=\dfrac{264}{\tan 46^{\circ}}\\\\\Rightarrow x=254.94\ ft[/tex]

Therefore, the two buildings are [tex]254.94\ ft[/tex] apart.

Answer:

1.5x= y

Step-by-step explanation:

Speed = distance / time

The variable x represents time in hours and y represents yuri's distance from home in miles.

Therefore

Speed = y/ x

But distance = 5 miles and  speed= 1.5 miles

1.5 = y/x

or

1.5x= y

Answer:

158 inches squared

Step-by-step explanation:

I am calling them Inches instead of centimeters because the image only shows inches as the unit.

To find the surface area, you need to add up all the rectangles' areas ([tex]lw[/tex]) shown to get the sum surface area.

Sides A & D: [tex]5 * 8 =40[/tex]

Sides B & F: [tex]3 * 8 =24[/tex]

Sides C & E: [tex]3 * 5 = 15[/tex]  (You get 5 inches from the edges, if you fold it into a rectangular prism, the side would have dimensions of 3x5.)

Then, you add all of the sides together.

[tex]A(40)+D(40)+B(24)+F(24)+C(15)+E(15)\\= 158[/tex]

Your total surface area would be 158 in.

Answer:

84 cm²

Step-by-step explanation:

3 x 4 x 0.5 = 6

3 x 4 x 0.5 = 6

3x 6 = 18

5 x 6 = 30

4 x 6 = 24

add up = 84

Step-by-step explanation:

let the smaller number be x

5x - x = 52

4x = 52

4x÷4 = 52÷4

x = 13

the smaller number is 13

the bigger number is 5×13 = 65
