Answer:
(x+4)(x+5)
Step-by-step explanation:
Use the sum-product pattern
2+ 9+ 20
2 + 5 + 4 + 20
Common factor from the two pairs
2 + 5 + 4 + 20
( + 5 ) + 4 ( + 5 )
Rewrite in factored form
( + 5 ) + 4 ( + 5 )
( + 4 ) ( + 5 )
Answer:
About 150 people.
Step-by-step explanation:
1.) 15/36 = x/360
2.) 150/360 = x/360
3.) 150/360 = 150/360
A straight line can be drawn through all the points and the line passes through the point where x=0 and y=0. This best describes a graph of paired points that form a proportional relationship. You can tell this because the line passes directly through the origin (0,0). It also says that it is a straight line that passes through the points, so most likely the line will contain points that have a proportional relationship. Hope that helps :)
Longer than the triangles , but shorter triangles, are bigger than eachother but same same and no different shape .
To find the product of (4x-5y)^2,
we can rewrite the problem as:
(4x-5y)(4x-5y) (two times because it is squared)
Now, time to use that old method we learned in middle school:
FOIL. (Firsts, Outers, Inners, and Lasts)
FOIL can help us greatly in this scenario.
Let's start by multiplying the 'Firsts' together:
4x * 4x = <em>16x^2</em>
Now, lets to the 'Outers':
4x * -5y = <em>-20xy</em>
Next, we can multiply the 'Inners':
-5y * 4x = <em>-20xy</em>
Finally, let's do the 'Lasts':
-5y * -5y = <em>25y</em>^2
Now, we can take the products of these equations from FOIL and combine like terms. We have: 16x^2, -20xy, -20xy, and 25y^2.
-20xy and -20xy make -40xy.
The final equation (product of (4x-5y)^2) is:
16x^2 - 40xy + 25y^2
Hope I helped! If any of my math is wrong, please report and let me know!
Have a good one.
