Answer: 4(4b - 5)(b + 5)
Step-by-step explanation:
All have a common factor of 4
4(4b^2 + 15b - 25)
--------------------------------------------------------------------------------------------------------------
Now you need to find two numbers that:
a) multiply to -100 (the a term * the c term = 4 * -25)
b) add to 15 (the b term)
After a little thinking, we can determine that the two numbers are:
20 and -5
--------------------------------------------------------------------------------------------------------------
Now we can rewrite the middle term as 20b - 5b (notice how it still equals 15b)
4(4b^2 + 20b - 5b - 25)
--------------------------------------------------------------------------------------------------------------
4((4b^2 + 20b) + (-5b - 25))
Group the terms (associative property)
--------------------------------------------------------------------------------------------------------------
Take out a common factor from each
4(4b(b + 5) - 5 (b + 5))
--------------------------------------------------------------------------------------------------------------
Now we can factor by grouping
4(4b - 5)(b + 5)
--------------------------------------------------------------------------------------------------------------

Answer:
volume: 200 cm³surface area: 220 cm²Step-by-step explanation:
The usual formulas are useful for this.
V = LWH
V = (10 cm)(4 cm)(5 cm) = 200 cm³
The volume is 200 cubic centimeters.
__
SA = 2(LW +H(L +W))
SA = 2((10 cm)(4 cm) +(5 cm)(10 cm +4 cm)) = 2(40 +5(14)) cm² = 220 cm²
The surface area is 220 square centimeters.

Step-by-step explanation:
Find the common denominator, then whatever it is, multiply the top to match it. For examples you start with 7/5 and you are trying to get the denominator to 25, you would multiply 7x5 which equals 35/25. Hope this helps.

Answer: You must rearange 3 3/4 into an improper fraction to make the subtraction easier.
Step-by-step explanation:
(this is a little long bear with me :3)
3 and 3/4ths into a improper fraction would be: 15/4
looking at 15/4 and 7/8 notice how the denominators are 4, and 8. both are common denominators. so we multiply 4x2 to make 4, into 8. and whatever we do to the bottom, we do to the top.
15x2 30
---------- = ------
4x2 8
our new fraction is 30/8.
do the subtraction..
30 7 23
---- - --- = --- that then turns into a mixed number, which is:
8 8 8
2 7/8.
hope this helped! :)
Answer:
