Answer:
![10(3x+7)](https://tex.z-dn.net/?f=10%283x%2B7%29)
Step-by-step explanation:
we have the expression:
![30x + 70](https://tex.z-dn.net/?f=30x%20%2B%2070)
To factor this expression we need to indentify the components that are common in both terms.
At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:
![10*3=30\\10*7=70](https://tex.z-dn.net/?f=10%2A3%3D30%5C%5C10%2A7%3D70)
so we can substitute this into the expression:
![10*3x+10*7](https://tex.z-dn.net/?f=10%2A3x%2B10%2A7)
and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:
![10(3x+7)](https://tex.z-dn.net/?f=10%283x%2B7%29)
If we round it
1) 7 people
2) 4 people
3) 5 people
Answer:
The length of the box is 10 feet.
Step-by-step explanation:
You have to work backwards to find volume, so just divide the volume (100) by the height (2) then divide that by the width (5) and you get your answer, 10
Answer:
<h3>1 secs</h3>
Step-by-step explanation:
Given the height of the discus can be modeled by the equation y=−16x
^2
+32x+4, where y represents the height in feet of the discus in seconds, the velocity of the discus at its maximum height is zero.
Velocity v = dy/dx = 0
dy/dx = -32x + 32
0 = -32x + 32
32x = 32
x = 1 secs
Hence it will take the discus 1 secs to reach its maximum height
