Each side is 4 feet
16 ft squared = 4 feet
4 times 4= 16
A square has 4 sides that are equal
Each side is 4 feet
The spring will be stretched 18.2 inches by force of 26 pounds.
Step-by-step explanation:
7 pound stretches the spring = 4.9 inches
Ratio of force to spring = 7:4.9
New force = 26 pounds
Spring stretched = x
Ratio of new force to spring = 26:x
Using proportion;
Ratio of force to spring :: Ratio of new force to spring
Product of mean = Product of extreme
Dividing both sides by 7
The spring will be stretched 18.2 inches by force of 26 pounds.

Answer:
D
Step-by-step explanation:
Consider the equation:
Use distributive property in both sides:
Separate terms with x into the left part and terms without x into the right part:
Since you get true equality 0 = 0, the equation is true for all real values of x. So, the equation has infinitely many solutions.
The factored form of the expression (49y² - 64) is ( 7y + 8 )( 7y - 8 )
<h3>What is the factored form of the given expression?</h3>
Given the expression in the question;
49y² - 64
To determine the form, let's break down 49y².
49 can be written as 7 × 7, y² can be written as y × y and 64 can be written as 8 × 8
Hence
49y² = 7y × 7y = (7y)²
64 = 8 × 8 = 8²
So we have,
(7y)² - 8²
Since both terms are perfect square, we can factor using the difference of square.
a² - b² = ( a + b )( a - b )
a is 7y and b is 8
(7y)² - 8² = ( 7y + 8 )( 7y - 8 )
Therefore, the factored form of the expression (49y² - 64) is ( 7y + 8 )( 7y - 8 )
