Answer:
<h3>
</h3>
Step-by-step explanation:
y= x²+6x-5
completing the square: <em> a²+2ab+b²</em> <em>= (a+b)²</em> where <em>a²=x² </em>(so <em>a=x</em>) and <em>2ab=6x </em> (so <em>b</em> would be 3):
Answer: 56in³
Step-by-step explanation:
Let the volume of solid B de denoted as x. Based on the information given in the question, we can solve further by:
1/2 = 28/x
Cross multiply
1 × x = 2 × 28
x = 56
Therefore, the volume of solid is 56in³.
Let one piece be x inches long then the other piece is 180-x inches long.
3x > 4 (180-x)
3x > 720 - 4x
7x > 720
x > 103 6/7 ins
the 2 pieces could be 107 inches and 180-107 = 73 inches
