y=(x+8)(x^2+8x+16) + 9

y=(x+8)(x+4)(x+4)+9

0=(</span>x+8)(x+4)(x+4)+9

x+8=0

x=-8

x+4=0

x=-4

I believe the answer is 2

The answer should be 1. Keep in mind that all cubic curves will always have at least 1 real zero. The embedded image is a graph of y=(x+8)³+9


The second answer should be y=xx^{4}-6xx^{3}+6xx^{2}-6x+5 (the last answer choice), as seen by the second image.

MA_775_DIABLO [31]

Answer:

5

Step-by-step explanation:

The clothing store already sold $300 .

They need to sell x jeans to get to $500.

$500 - $300

$200

They’re $200 short of their goal.

A pair of jeans cost $40

Therefore x40 = $200

x = 200/40

x = 5

So ,they need to sell 5 pairs of jeans to hit their $500 target

What's the area of this? PLS HELP
balandron [24]

Answer:

446mm

Step-by-step explanation:

If we box off parts of the area, it makes it easier to solve. I personally broke it into tiny bits:

Upper left box: 16mm

Bigger box (excluding little box): 90mm

Big rectangle: 340mm

Now, add them all together.

Equals 446mm
