Answer:

a) x = 3.0625m

  y = 45.9375 m

b) A = 140.68359375 m²

Step-by-step explanation:

Let x be the length

Let y be the width

2x + 2y = 98

x + y = 49

y = 3(5x)

y = 15x

x + 15x = 49

16x = 49

x = 3.0625 m

y = 15(3.0625) = 45.9375

A = xy = 3.0625(45.9375) = 140.68359375

What are the zeros of the polynomial function? f(x)=x^3+x^2−9x−9
ella [17]

Answer:

1: x = -1

2: x = 3

3: x = -3

Step-by-step explanation:

f(x)=<u>x^3+x^2</u>−9x−9

f(x)=x^2<u>(</u>x+1) <u>−9x−9</u>

f(x) = x^2<u>(x+1)</u> - 9<u>(x+1)</u>

f(x)= (x+1)<u>(x^2-9)</u>

f(x) =(x+1)(x-3)(x+3)

Simple proportions.

You want a 1:5 ratio.
You have a 5:1 ratio.
So you add another 24 drops of white.
5:25 = 1:5 
or
5/x = 1/5 and cross multiply.
