Answer: The correct options are

(1) Figure A.

(2) Figure B.

(3) Figure C.

Step-by-step explanation: We are given to select the figures that are polygons.

<u>POLYGON :</u> A polygon is a plane shape with straight sides having number of sides greater than or equal to three.

In Figure 1, there are three straight sides, so it is a polygon with three sides. We call it a TRIANGLE

In Figure 2, There are four straight sides, so it is a polygon with four sides. We call it a QUADRILATERAL.

In Figure 3, there are six straight sides, so it is a polygon with six sides. We call it a HEXAGON.

In Figure 4, there is no straight side, and hence the figure is NOT a polygon.

Thus, the correct Figures are A, B and C.

Options (1), (2) and (3) are correct.

Please help me on my math

Answer:

m = -8

b = -24

Step-by-step explanation:

To solve this problem use the hint and put this equation in y = mx + b form. This is called slope-intercept form.

In slope-intercept form, the coefficient of x (which is m) is the slope of the line and b is the y-intercept of the line.

-32x - 4y = 96

Add 32x to both sides of the equation.

-4y = 32x + 96

Divide both sides of the equation by -4.

y = -8x - 24

Comparing this to y = mx + b, the -8 is "m" and -24 is "b". Therefore your final answers are:

m = -8

b = -24

Solve the following equation 1÷x=2

Troyanec [42]

Answer:

Your answer would be x = 1/2

Step-by-step explanation:

1/x = 2

You would divide x on both sides...then they would cancel each other out.

But now you're left with...

1 = x•2

So, re-order the terms so constants are on the left

1 = 2x

Divide 2 on both sides...

Now you're left with

1/2=x or more practically it would be x = 1/2

Hope this helps!

Your family is installing a new square pool in the backyard. The existing patio has a side length of 8 feet. How much of the pat

trasher [3.6K]

The question is an illustration of perimeters.

The amount of patio to remove to install the pool is 8 feet.

From the question, we have:

$\mathbf{Length\ of\ the\ pool = 8}$

$\mathbf{Length\ of\ walkway = 1}$

The perimeter of the patio is:

$\mathbf{P_p = 4 \times Length\ of\ the\ pool}$

$\mathbf{P_p = 4 \times 8}$

$\mathbf{P_p = 32}$

A 1ft walkway means that;

1ft would be subtracted from both sides of the patio before installing the pool

So, the perimeter of the patio in terms of the length of the pool is:

$\mathbf{P_p = 4 \times (x +2)}$

Equate both expressions

$\mathbf{P_p = P_p}$

$\mathbf{4 \times (x +2) = 32}$

Divide both sides by 4

$\mathbf{x +2 = 8}$

Subtract 2 from both sides

$\mathbf{x = 6}$

So, the perimeter of the pool is:

$\mathbf{P_{pool} = 4 \times 6}$

$\mathbf{P_{pool} = 24}$

The amount of patio to remove is:

$\mathbf{Amount = P_p - P_{pool}}$

So, we have:

$\mathbf{Amount = 32 - 24}$

$\mathbf{Amount = 8}$

Hence, 8ft of the patio would be removed to install the pool
