Answer:

PEMDAS” (parenthesis, exponents, multiplication, division, addition, subtraction) to help you remember? Memorable acronyms aren't the only way to memorize concepts.

Step-by-step explanation:  -> 3 x 2 +( 4 - 1) = ??

always when you see these in your equation you always start with these>>>(4-1=3) then 3x2=6 then you add that then you get 9

9 is your answer hope this helps

Answer:

The answer is 9.

Step-by-step explanation:

PEDMAS stands for :

  • \purple\star P = Parentheses
  • \purple\star E = Exponents
  • \purple\star M = Multiplication
  • \purple\star D = Division
  • \purple\star A = Addition
  • \purple\star S = Subtraction

To solve the given equation we will follow the PEDMAS rule.

\begin{gathered}\qquad{\twoheadrightarrow{\sf{3 \times 2 + (4 - 1)}}} \\  \\ \qquad{\twoheadrightarrow{\sf{3 \times 2 + (3)}}} \\  \\ \qquad{\twoheadrightarrow{\sf{3 \times 2 + 3}}} \\  \\ \qquad{\twoheadrightarrow{\sf{6+ 3}}} \\  \\ \qquad{\twoheadrightarrow{\sf{9}}} \\  \\ \qquad{\star\underline{\boxed{\tt \pink{ \: 9 \: }}}}\end{gathered}

Hence, the answer is 9.

What is the equation of the line that is perpendicular to y, =, 1 over 3 x, 4. And contains the point negative 2, negative 5,?.
Anit [1.1K]

The equation of the line is, \rm y = 3x + 1.

Given that,

The equation of the line is,

\rm y = \dfrac{1}{3} x+4\\

And contains the point (-2, -5).

We have to determine,

What is the equation of the line that is perpendicular to the given line?

According to the question,

The equation of the line is,

\rm = \dfrac{1}{3}x + 4\\

On comparing with the standard equation of the line y = mx +c.

The slope of the line m_1 is 1/3.

When two lines are perpendicular the relation between these slopes is,

\rm m_1\times m_1 = {-1}\\\\\dfrac{-1}{3} \times m_2 = -1\\\\-1 \times m_2 = -1 \times 3\\\\-m_2 = -3\\\\m_2 = 3

And line contains the point (-2, -5).

Then,

\rm y = mx +c \\\\-5 = 3 (-2) + c\\\\-5 = -6+c \\\\c = 6-5 \\\\c = 1

Therefore,

The equation of the line that is perpendicular to the given line and contains the point (-2, -5) is,

\rm y = mx +c \\\\y = 3x +1

Hence, The required equation of the line is, \rm y = 3x + 1.

elixir [45]

Answer:

you have 96 feet of fencing to enclose a rectangular pen for your dog. the pen should be three times long as it is wide. write a
swat32

Answer:

length = 36 ft; width = 12 ft

Step-by-step explanation:

Let the width be x.

The length is 3x.

The perimeter is the sum of two lengths and two widths, and it equals 96 ft.

3x + 3x + x + x = 96

8x = 96

x = 12

Width = x = 12 ft

Length = 3x = 3(12 ft) = 36 ft
