Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
(x + 1)² - 25/9 = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 25/9 on both sides: (x + 1)² = 25/9
- [Equality Property] Square root both sides: x + 1 = ±5/3
- [Subtraction Property] Subtract 1 on both sides: x = ±5/3 - 1
- Evaluate Addition/Subtraction: x = 8/3, 2/3
Answer:
The dimensions of the desk are
Length: 54 inches
Width: 30 inches
Step-by-step explanation:
we know that
The area of rectangle is equal to
where
L is the length
W is the width
we have
so
----> equation A
----> equation B
substitute equation B in equation A
solve for W
Solve the quadratic equation by graphing
The solution is W=30 in
see the attached figure
<em>Find the value of L</em>
therefore
The dimensions of the desk are
Length: 54 inches
Width: 30 inches
Answer: The answer is B

Answer: The probability of an odd number is 1/2, and the probability of a tail is also 1/2, so the probability of both occurring is the product, 1/4.
Step-by-step explanation: The coin is fair, the probabilities of getting a head and a tail are equal to 12 . The probability of getting an even number on a die is 36=12 because among 6 results there are 3 even numbers
