ห - 14W - 32<br> I’m factoring polynomials please help
nydimaria [60]

Answer:

Step-by-step explanation:

Sum = -14

Product = - 32

So, the factors = -16 , 2

When we add -16 +2 = -12 and when we multiply it is -32

w⁴ - 14w² - 32 =  w⁴ - 16w² + 2w² - 16 * 2

                      = w²(w² - 16) + 2(w² - 16)

                      = (w² - 16)(w² + 2)

                      = (w² - 4²)(w² + 2)

                      = (w + 4)(w - 4)(w² + 2)

What is the approximate value of x in this figure?<br> 19 POINTS
Sladkaya [172]

Answer:

4.69 inches (2 decimal places)

Step-by-step explanation:

Refer to image attached to this answer:

Using Pythagoras Theorem:

AB^2+AC^2=BC^2

2^2+3^2=BC^2

4+9=BC^2

BC^2=13

-------------------------

Using Pythagoras Theorem,

BC^2+CD^2=BD^2\ (x)

13+3^2=BD^2

13+9=BD^2

BD=\sqrt{22} = 4.69\ (2d.p.)

Solve by substitution. Please show work<br> -x+9y=-5<br> x-5y=1
kkurt [141]

Let's solve for x.

−x+9y=−5

Step 1: Add -9y to both sides.

−x+9y+−9y=−5+−9y

−x=−9y−5

Step 2: Divide both sides by -1.

−x ÷ −1 = −9y−5 ÷ −1

x=9y+5

THE ANSWER FOR THE OTHER EQUATION: (x-5y=1)

Let's solve for x.

x−5y=1

Step 1: Add 5y to both sides.

x−5y+5y=1+5y

x=5y+1

Answer:

x=5y+1

I hope this helped I was a little confused on what your problem meant...so if this is not what you asked for just lmk so I can fix it for you :)
