The expression would be 2(3x + 9) + 2(4x - 5). Simplified, it is 14x + 8.

Answer:

14 x+8

Step-by-step explanation:

Parallelogram:  A parallelogram is a special type  of quadrilateral  in which opposite sides are equal and parallel.

We have to find  the perimeter of parallelogram

Perimeter of parallelogram= sum of all four sides

Let first side= 3 x+9

Second side= 4 x-5

third side= 3 x+9

fourth side side= 4 x-5(opposite sides of parallelogram are equal)

Perimeter=  3 x+9+ 4 x-5+ 3 x+9+ 4 x-5+

Perimeter= 14 x+ 8

Hence, Perimeter of parallelogram= 14 x+8

'The quotient of a number and 6 minus 3 is 1​
lianna [129]

Answer:

x=24

Step-by-step explanation:

The Quotient(dividing) of a number(x) and 6 minus(-) 3 IS(=) 1.

Which turns into:

\frac{x}{6} - 3 = 1

We want to get x by itself so we divide the entire equation by 6.

6 ( \frac{x}{6} - 3 = 1 )

x - 18 = 6

We want to move the plain numbers to one side so x can be by itself. So we add 18 to both sides.

x = 24

I need help before with this before 12:00 am
frutty [35]

Answer:

7.18 light-years

Step-by-step explanation:

6.8 x 10^13 = 68,000,000,000,000

9.46 x10 ^12 = 9,460,000,000,000

6.8 x 10^13  *  1 light year / 9.46 x 10^12 = 7.188 light years.

Shane wrapped the kite with paper. How many square inches of paper did Shane use to cover the front and back? 45 POINTS
arsen [322]

Answer:

576

Step-by-step explanation:

First off, we can use the area of a kite formula, (D1*D2)/2 to get the area of one side of the kite, which is simplified to 18 * 32 : which gets us 288. But because we are looking for the area of the front and back side, we multiply 288 by 2- getting the final answer of <u>576</u>.

A ladder is leaning against
Svetradugi [14.3K]

Answer:

25 ft

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

15^2 + 20 ^2 = x^2

225+400= x^2

625 = x^2

Take the square root of each side

sqrt(625) = sqrt(x^2)

25 = x
