Answer:
1/7
Step-by-step explanation:
you divide both numbers by 4
20% of $175 is $35. Divided between 5 people (35/5=7) would be 7. So each person should tip $7.
if you are looking for.... 2(B-4)= (6)b
2b - 8 = 6b
2b - 6b= 8
-4b=8
so b= -2
the question is b-4 divided by 6 equals b/2
(1,-10)
the 10 must be negative
reason why the others dont work:
(1,10) too positive, the other two start negative, no way is it going to be way up here
(10,1) still too high
(-1,10) then again, too high
Answer:
We have expanded formula of (-4x-1)² = a²+2ab+b².
So, we write the formula in square form as (a+b)².
Since we have a²-b² in step 4. We further write this as (a+b)(a-b). This is the factor formula of a²-b².
As we had two terms in place of in (a+b)(a-b), we multiply the term 'b' with '+' and '-' sign respectively.
Write the second expression given in the question.
Write the terms in the form of cube.
Write the factor formula of a³-b³) in the form of (a-b)(a²+ab+b²).
Write the H.C.F. (Highest Common Factor) of the given expressions by analysing the factors you generated in each expressions. Here, (4x²+2x+1) are the common factors.
