Combining like terms with negative coefficients -3x-6+(-1)

Mathematics
1 answer:
Verdich [7]3 years ago
6 0

Step-by-step explanation:

Hey there!!

You can simply do it.

Here, -3x -6 +(-1) is given.

In this question, the like term is "-6" and "-1" because both are coefficients.

Combine it.

= -3x -6 -1 { as (-) (+)=(-)}

= -3x -7 { when there is (-) sign then it will be added but the sign would be minus}.

Or you can also write it as -( 3x+7). {taking (-) common}

Find the area of this circle. Use 3 for a.A = 7r2=11 in[?] in?
liberstina [14]

SOLUTION

We want to find the area of the circle in the picture given.

We have been given the formula as

\begin{gathered} A=\pi r^2 \\ We\text{ are told to take }\pi\text{ as 3} \\  \end{gathered}

From the circle, the radius r = 11 in.

The area of the circle becomes

\begin{gathered} A=\pi r^2 \\ A=\pi\times r^2 \\ A=3\times11^2 \\ A=3\times11\times11 \\ A=363in^2 \end{gathered}

Hence the answer is 363 square-inches

Joseph wants to line his garden with a fence that cost $2.25 per foot. The length of the garden is 6 yards and the width is 2.5
Galina-37 [17]

Answer:

$38.25

Step-by-step explanation:

Perimeter of a rectangle = 2W + 2L

(where W is the width and L is the length)

Given:

  • width = 2.5 yd
  • length = 6 yd

⇒ perimeter = (2 x 2.5) + (2 x 6)

                     = 5 + 12

                     = 17 yd

Given:

  • cost of fence = $2.25 per foot

⇒ total cost = 17 x 2.25

                    = $38.25
