Answer:

<em>x</em> = 3.5

Step-by-step explanation:

P= 55

l= 2x+4

W= 3x+6

P= 2(L+W)

55= 2(2x+4+3x+6)

55=2(5x+10)

55=10x+20

35=10x

3.5=x

Step-by-step explanation:

P = 2(l+b)

55 = 2(2x+4 + 3x + 6)

55 = 2( 5x + 10)

55= 10x +20

10x = 55 - 20

X = 35/10

X = 7

What is the coefficient of x2 in the expansion of (x + 2)3?
wolverine [178]
One way is that you can just factor it out: (x+2)(x+2)(x+2)
For the first pair, you get x^2+4x+4.
Then do (x^2+4x+4)*(x+2)
That will be x^3+6x^2+12x+8
So the answer is 6

Lesson 2-3
malfutka [58]

Answer:

18. g= -3

19. x= -1

20. n= 3

21. p= -1

22. d= -3

23. a= 5

Step-by-step explanation:

how to solve the variable (using 18 as an example)

step 1: simplify both sides of the equation.

20+g+g=14

(g+g)+(20)=14(combine like terms)

2g+20=14

2g+20=14

step 2: subtract 20 from both sides.

2g+20−20=14−20

2g=−6

step 3: divide both sides by 2.

2g/2 = -6/2
