W=x
L=2x+17

Double everything since we need to lengths and two widths to find the perimeter

2x+17+2x+17+x+x = 76
Combine like terms

6x+34=76
Solve for x
First step is subtract 34 from both sides

6x=42
Next you divide both sides by 6 in order to get x by itself

X=7

Now you plug in 7 into the x’s in length and width

W=7 cm
L=31 cm

THE WIDTH IS 31 CM

Check:

7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.

N=3, zeros 4 and 2i, f(2)=-48 find nth degree polinomonal function
enot [183]
The degree is 3, the zeros are; 4, 2i, -2i and a point is (-48, 2) 

For zeros; 2i, -2i <-- complex conjugates, always in pairs 

\frac{c}{a}=(2i)(-2i) &#10;
= -4(i²=-1)
=5 

\frac{b}{a}=-(2i+(-2i))
=0 

Therefore the equation is; a(x^{2}+5) <-- b value is zero 

Rewrite the equation with all zeros; 

a(x-4)(x²+5)=f(x) <-- put in coordinates of the points to find the value of x
a(2-4)(2²+5)=-48 
a(2)(9)=-48 
a=-48/18 
a=-8/3 

The final polynomial function is; (-8/3)(x-4)(x²+5)=f(x)

Hope I helped :)

Solve for x.
Maksim231197 [3]

Answer:

1. 9x+4<58

x<6

2. 1x-2>3

x>1

Step-by-step explanation:

1. 9x+4<58

First, you need to group all the like terms ( the group of numbers that have the same variable), Also remember that, when a positive number crosses an inequality symbol, it becomes negative.

9x<58-4

Then, subtract the two numbers.

9x<54

Divide x's coefficient by 54 and you have your answer.

x<6

2. 1x-2>3

First, you need to group all the like terms. Remember that, when a negative number crosses an inequality symbol, it becomes positive.

1x>3-2

Then, subtract the two numbers.

1x>1

1 divided by one is one, so

x>1

Mark wrote the highest score he made on his new video game as the product of 70 X 6000. Use the Associative and Commutative Prop
sesenic [268]
I think in commutative properties of multiplication:
70 x 6000 = 70 x 6000
420,000   =  420,000

I don't know associative properties, only commutative properties. Sorry :(
