The answer to the expressions are

-5 - 9x - 8x + 2 = -3 -17x

6k - k = 5k

4 - 5(-8 + 2w) = 44 - 10w

8n + 2n - 3 = 10n -3

-5(7p - 3) - 2 = -35p + 13

To solve the question, we will simplify all of the expressions.

For the first expression, -5 - 9x - 8x + 2 = ?

First, collect like terms

-5 + 2 - 9x - 8x = -3 -17x

∴ -5 - 9x - 8x + 2 = -3 -17x

For the second expression, 6k - k = ?

6k - k = 5k

For the third expression, 4 - 5(-8 + 2w) = ?

First, clear the brackets

4 - 5(-8 + 2w) = 4 + 40 -10w

= 44 - 10w

∴ 4 - 5(-8 + 2w) = 44 - 10w

For the fourth expression, 8n + 2n - 3 = ?

8n + 2n - 3 = 10n -3

∴ 8n + 2n - 3 = 10n -3

For the fifth expression, -5(7p - 3) - 2 = ?

First, clear the bracket

-5(7p - 3) - 2 = -35p + 15 -2

= -35p + 13

∴ -5(7p - 3) - 2 = -35p + 13

Hence, the answer to the expressions are

-5 - 9x - 8x + 2 = -3 -17x

6k - k = 5k

4 - 5(-8 + 2w) = 44 - 10w

8n + 2n - 3 = 10n -3

-5(7p - 3) - 2 = -35p + 13

Triangle def is equilateral. If the perimeter of def is 36, the length of de is 5x-8, then what is the value of x

My name is Ann [436]

Answer:

Step-by-step explanation:

All the sides of an equilateral triangle are equal, hence the perimeter is expressed as P = 3s

s is one of the side length

Given DE = 5x - 8

P = 3DE

P = 3(5x-8)

36 = 3(5x-8)

36/3 = 5x-8

12 = 5x - 8

5x = 12+9

5x = 20

x = 20/4

x = 4

Hence the value of x is 4

The three sides of a triangle are n, 3n+3, and 2n+11. If the perimeter of the triangle is 50 inches, what is the length of each

mylen [45]

Answer:

6, 21, and 23 inches

Step-by-step explanation:

The perimeter of a triangle is equal to the sum of all side lengths in that triangle. We're given the perimeter as 50 inches, and the side lengths as n, 3n + 3, and 2n + 11.

This means that we can algebraically solve the equation $n + 3n + 3 + 2n + 11 = 50$

Step 1: Combine like terms.

$(n+3n+2n) + (3+11) = 50$
$6n + 14 = 50$

Step 2: Subtract 14 from both sides.

$6n + 14 - 14 = 50 - 14$
$6n = 36$

Step 3: Divide both sides by 6.

$6n/6 = 36/6$
$n = 6$

Step 4: Plug in the value of n as 6 in each side.

$(6) + (3(6) + 3) + (2(6)+11) = 50$
$(6) + (18+3) + (12+11) = 50$
$(6) + (21) + (23) = 50$

Therefore, the side lengths are 6, 21, and 23 inches.
