Answer 1

Answer:

the answer is B) 12a+6b

Step-by-step explanation:

3+9=12 so 3a+9a=12a,

7-1=6 so 7b-(1)b=6b

Answer 2

Step-by-step explanation:

calm down ! just breathe.

these are totally simple additions and one also very simple subtraction to make.

you know that you can combine terms based on the same variable, right ?

3a + 9a = 12a

7b - b = 6b

the result is then

12a + 6b, so B is the right answer.

this bases already on the same principle of actual numbers.

2×3 + 5×3 = 7×3 because this is also

(2 + 5) × 3

6×5 + 6×3 = 6×8 because this is also

6 × (5 + 3)

7×8 - 4×8 = 3×8 because this is also

(7 - 4) × 8

and so on.

Answer:

x = 38.2

Step-by-step explanation:

Each of the functions of x represents the measure of an angle in the triangle. You write an equation for x by using what you know about the relationships of angles in a triangle: their sum is 180°.

(2x) +(x -18) +(2x +7) = 180

What is the image of the point (- 6, 1) after the reflection over the line y = 2 ?
A. (- 4, 1)
В. (10, 1)
C.(- 6, 3)
D.(- 4, 3)

Answers

It will be c. (-6, 3)

The image point is (-6, 3).

What is the image point?

According to tradition, the "image" of point P is the reflection of point P across the line, which is designated by the term P' (pronounced "P prime").

The reflection of point (a,b) with respect to line y=k is point (a, 2k -b)

To find the image of the point (-6 ,1);

The formula:

(a, b) → (a, 2k-b)

Here a=-6, b = 1, k = 2

therefore (-6, 1) → (-6, 2×2 (-1))

= (-6, 3)

Hence, the answer is (-6, 3).

The regular hexagon has a radius of 4 in. A regular hexagon has a radius of 4 inches. What is the approximate area of the hexagon? 24 in. 2 42 in. 2 48 in. 2 84 in. 2.

Answers

The approximate area of the hexagon is 48 square inches.

Given that the regular hexagon has a radius of 4 inches, to determine what is the approximate area of the hexagon the following calculation must be performed:

Area of a regular hexagon = (perimeter x apothem) / 2 (4 x 6 x 4) / 2 = X (24 x 4) / 2 = X 48 = X

Therefore, the approximate area of the hexagon is 48 square inches.

Two side of a triangle are 26 and 27, while the height to the third side is 25. Find the area of the triangle.

Answers

Based on the information given, the area of the triangle is 291.85.

From the information given,

A = 26

A = 26B = 27

A = 26B = 27C = 25

Firstly, we'll add the sides given and divide them by 2. This will be:

S = (26 + 27 + 25) / 2

S = 78/2

S = 39

Then we will use the formula:

= s(s - a)(s - b)(s - c)

= 39(39 - 26)(39 - 27)(39 - 25)

= 39(13 × 12 × 14)

= 85176

Lastly, we'll find the square root of the value gotten. This will be:

= ✓85176

= 291.85.

Therefore, the area is 291.85.
