Answer:

x = -20

Step-by-step explanation:

1st Subtract 8 from both sides: 84/5(15+2x)-8=-12-8

2nd Simplify: 4/5(15+2x)=-20

3rd Multiply both sides by 5: 5×4/5(15+2x)=5(-20)

4th Simplify: 4(15+2x)=-100

5th Divide both sides by 4: 4(15+2x)÷4=-100÷4

6th Simplify: 15+2x=-25

7th Subtract 15 from both sides: 15+2x-15=-25-15

8th Simplify: 2x= -40

9th Divide both sides by 2: 2x÷2=-40÷2

10th Simplify: x = -20

ANSWER ASAP GIVING BRAILIEST AND STUFF!
natita [175]

Answer:

24s^2, 54s^2, 96s^2

Step-by-step explanation:

Let s represent the initial side length of the cube.  Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).

a) Now suppose we double the side length.  The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),

b) tripled:  A = 6(3s)^2 = 54x^2

c) quadrupled?  A = 6(4s)^2 = 96s^2

Find the value of x. Round the length to the nearest tenth.
larisa [96]

Answer:

x = 7.9

Step-by-step explanation:

Given:  

Angle - 44

Hypotenuse - 11 ft

adjacent side - x

having adjacent and hypotenuse use Cosine to solve the problem from

S-oh C-ah T-oa

cos (angle) = adjacent / hypotenuse

**Make sure your calculator is in degree mode**

cos 44 = x/11

if you cross multiply, you get

11 cos 44 = x

or to solve for x you would multiply both sides by 11 and get

11 cos 44 = x

x = 7.9

Could someone answer this pls thank u

Given:

The area model.

The area of the shape is 82 square units.

To find:

The correct equation for the given situation.

Solution:

We know that, area of a rectangle is

Area=Length \times Width

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is

A_1=(x)\times (3x)=3x^2

A_2=(x)\times (4)=4x

A_3=(3)\times (3x)=9x

Now, the total area is equation to 82 square units.

A_1+A_2+A_3=82

3x^2+4x+9x=82

3x^2+13x=82

Since the required equation is 3x^2+13x=82, therefore, the correct option is C.
