Answer:
4(a + 6)
3(x - 4)
Step-by-step explanation:
Factoring is just rewriting an expression into the parts that multiply together to make the original...like if I had a 100 but decided instead to write 4×25 or if I had 25x I wrote 5(5x) .
If you look at your
4a + 24
You're looking for whatever is the same in both pieces (the 4a and also the 24) So there is a 4 in 4a and there is also a 4 "in" 24 (as in 4×6 is 24)
So if you pull out that 4 and throw it up front, whatever is left behind goes into a pair of parentheses.
4 (____ + ____)
4(a + 6)
This is your factored form bc if you multiply that 4 back in you'll get the original expression back again.
4a + 24
= 4(a + 6)
It's like factoring is "un-distributive" property.
Theres a 3 in 3x and also in 12
3x - 12
= 3(x - 4)
Answer:
a)10
b)5120
Step-by-step explanation:
Given that number of ants double after every ten days, form a table that shows numbe of ants from day 1 to day 91
Day Number of Ants
1 10
11 20
21 40
31 80
41 160
<em>51 320-----------------given</em>
<em>61 640------------------given</em>
<em>71 1280----------------given</em>
81 2560
91 5120
Using the given values for number of ants and the number of days, you can notice the trend for values of days and number of ants.After every ten days, number of ants doubles.Using this information, you can navigate backwards up to day 1 and forward up to day 91
The answer would be X=5 because 40 - 22 is 18
