</h3>
Step-by-step explanation:
2x² = - x² - 5x - 1
<u>Rearrange the terms and simplify</u>
That's
2x² + x² + 5x + 1 = 0
3x² + 5x + 1 = 0
Using the quadratic formula solve the equation
That's
<h3>

</h3>
From the question
a = 3 , b = 5 , c = 1
So we have
<h3>

</h3>
We have the final answer as

Answer:
Answer: She can make 9 steps from the rope.
Step-by-step explanation:
Given : The width of each step of the ladder = 2\dfrac{1}{3}\text{ feet}2
3
1
feet = \dfrac{2(3)+1}{3}=\dfrac{7}{3}\text{ feet}
3
2(3)+1
=
3
7
feet
The length of the rope = 21 feet
Then , the number of required steps = ( length of the rope ) ÷ (width of each step of the ladder)
=21\div\dfrac{7}{3}=21÷
3
7
=21\times\dfrac{3}{7}=3\times3=9=21×
7
3
=3×3=9
Hence, the number of steps can she make from the rope = 9.
