The answer would be 18 because if you put 3a+6a+a=180 (the degrees of a triangle) and solve it a becomes 18
$9.00 per hour. take 45 and divide by 5 you get 9.
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)
Price of a cone after tax = 14.58/6 = 2.43
Price before tax = 2.43 - 0.17 = 2.26
In short, Your Answer would be $2.26
Hope this helps!
Given:
The equation is
The incorrect solution steps are given.
To find:
The first error.
Solution:
We have,
Using distributive property, we get
The given step 1 is 
, which is not correct.
Therefore, there is first error in step 1 because the distribution property is not used properly.
Hence, the correct option is D.
