Answer 1

Answer:

214.08 cm²

Step-by-step explanation:

To find the whole area of an irregular polygon, you must first break it into polygons that are findable. For this figure, we can break it up into two figures, a triangles and a rectangle. To find the triangle, we must first find the height of it. To get that, we take the length of the blue line (the height of the entire figure), and subtract the height of the rectangle (9.6 cm) to  get a height of 5.7 cm for the triangle. the area formula for a triangle is 1/2 of the base multiplied by the height. To get the base of the triangle, we add the base of the rectangle to the parts of the triangle that hang past it (6.2 cm in total). 6.2 + 12.8 gives us 19 cm. Now we have (19 x 9.6) divided by 2 to give us 91.2 cm². The area formula for a quadrilateral is just the base (12.8 cm) multiplied by the height (9.6 cm), to give us 122.88 cm². Add the area of the rectangle to the area of the triangle to get our answer, 214 cm².

please help asap :((

Answers

Answer:

x = -2

x = 2

x = ?/2

x = ?(2)

Step-by-step explanation:

For each problem you want to isolate the variable.

For x + 2 you want to move the 2 by subtracting it (since it is being added to the x) from each side. Assuming the other side of the equal sign is 0, the answer is -2.

Same thing for x - 2, isolate by adding the 2 (since it is being subtracted).

For 2x and x ÷ 2 it is a little different. If we assume the opposite side is 0, the answer will be 0 because 0 divided or multiplied by 2 will give you 0. But if the opposite side is a different number, the answer will be that number and then the respected equation for the problem (divide both sides by 2 in 2x because the x is being multiplied by the 2 and multiple both sides by 2 in the x ÷ 2 because the x is being divided by the 2).

Use a composite figure to estimate the area of the figure.
A) about 14 square units
B)about 18 square units
C)about 11 square units
D) about 8 square units

Answers

A) about 14 square units

You have 11 fully filled squares 2 that are mostly filled and 2 that are about half filled

So 11+2+2(1/2)= about 14

Answer:

A) about 14u^2

Step-by-step explanation:

If you combine the two part filled units at the top of the figure, you can see that it makes a full unit.

The visual area is 15, so when you combine the part filled units, it will be about 14.

The greatest common factor (GCF) of 24 and 9 is 3. By taking out a 3 from the quantity, you get a -8 from the -24 and a 3w from the 9w. But the 3 doesn't disappear. It is put outside of the quantity to indicate that it has been taken out and can be put back in.

What is the length of the dotted line in the diagram below? Round to the nearest tenth.

Answers

Using the Pythagorean Theorem, it is found that the length of the dotted line in the diagram below is of 8.6 units.

What is the Pythagorean Theorem?

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem:

The length of the dotted line is the hypotenuse of a right triangle with legs 7 and x.x is the hypotenuse of a right triangle with sides 3 and 4.

Hence, the value of x is found as follows.

[tex]x^2 = 3^2 + 4^2[/tex]

[tex]x^2 = 25[/tex]

[tex]x = \sqrt{25}[/tex]

[tex]x = 5[/tex]

Then, the length l of the dotted line is found as follows.

[tex]l^2 = 5^2 + 7^2[/tex]

[tex]l = \sqrt{74}[/tex]

[tex]l = 8.6[/tex]

The length of the dotted line in the diagram below is of 8.6 units.
