[18].Simplify (TTE): x(2x+y+5) - 2(x²+xy+5) + y(x + y) <br>

Dovator [93]

Answer:

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10 + y\²$

Step-by-step explanation:

Given

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y)$

Required

Simplify

We have:

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y)$

Open brackets

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²+xy+5x - 2x\²-2xy-10 + xy + y\²$

Collect like terms

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²- 2x\²+xy-2xy+ xy+5x -10 + y\²$

$x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10 + y\²$

Fill in the steps to solve the log log base x of (2x)^3=6

arsen [322]

Answer:

x=2

Step-by-step explanation:

logx (2x)^3 = 6

We can rewrite without the exponent

3 logx (2x) = 6

Divide by 3

3/3 logx (2x) = 6/3

logx (2x) = 2

Raise each side to the base x

x^ logx (2x) =x^ 2

2x = x^2

Subtract 2x from each side

2x-2x = x^2 -2x

0 = x^2 -2x

Factor an x

0 = x(x-2)

Using the zero product property

x =0 x-2 =0

x =0 x=2

We cannot have a base of 0, so x cannot equal 0

x=2
