Answer:

$(y - 1)(x + y + 1)$

Step-by-step explanation:

$y(x + y) - 1(1 + x)$

Lets expand it.

$= > xy + {y}^{2} - x - 1$

Lets re-arrange it.

$= > xy - x + {y}^{2} - 1$

Lets split ${y}^{2} - 1$

So,

$= > x(y - 1) + (y + 1)(y - 1)$

$= > (y - 1)(x + y + 1)$

What expressions are equivalent to z + (z + 6)z+(z+6)

Mariana [72]

$z^{2} + 8z + 6$

Simplifying:

z + (z + 6)z + z + 6=

$z + z^{2} + 6z + z + 6$ =

$z^{2} + 8z + 6$

Elena has $225 in her bank account. She takes out $20 each week for weeks. After weeks she has d dollars left in her bank accoun

leonid [27]

Answer:

the equation to use would be D (255-20(5) = ?). To solve, first multiply 20 and 5 and you would get 100 so the equation would be 255 - 100 = ? Then you would subtract 100 from the 255 to get $155 left. To solve for 7 weeks you would replace the 5 in the equation with 7 so your equation would be 255 - 20(7) = ? Next you would multiply 20 and 7 to get 140. the equation would then be 255 - 140 = ? Subtract 140 from 255 and you would get 115. So after 7 weeks she would have $115 left in her account.

Help pleaseee and explain how , I’m confused thanks

Answer:

The rope is worth 13.

The shoe is worth 5.

The clock is worth 3.

Step-by-step explanation:

We know that the weights are 8 so we will use 8 for the weights.

Let s = show

Let r = rope

Let c = clock

We have three unknowns so we need three equations.

8 + s = r c + s = 8 s= c +2

There are a number of ways that we can approach this. Let's substitute

c + 2 for s in the first 2 equations.

8 + s = r

8 + c + 2 = r

10 + c = r

c + s = 8

c + c + 2 = 8

2c + 2 = 8

2c = 6

c = 3 we found the value of the clock.

Now, let's substitute 3 in for 3 in the bold equation above.

10 + c = r

10 + 3 = r

13 = r we found the value of the rope.

We can use any of the equations to find the shoe.

s= c + 2

s = 3 + 2

s = 5

This is tricky. It takes a lot of practice. Don't give up!
