-3.75 +4.35 -6.55
-3.75 + 4.35 = 0.6
0.6 - 6.55 = - 5.95
- 3.75 + 4.35 - 6.55 = - 5.95
We are given : 5a^2-25a
Please note: We always check Greatest Common Factor (GCF) first when factoring a polynomial.
If Greatest Common Factor (GCF) exist we factor out GCF.
In the given polynomial, we can see that greatest common factor of 5a^2 and 25a is 5a.
So, we would factor out GCF 5a first.
In order to factor out GCF, we need to divide all terms of the polynomila by GCF we got.
If we factor out 5a from 5a^2 -25a, we need to divide 5a^2 and -25a by 5a.
On dividing 5a^2 by 5a we get a and
on dividing -25a by 5a we get -5.
Therefore, on factoring out 5a, we get
5a(a-5).
Therefore, we use Greatest Common Factor (GCF) method of factoring.
When u divide 0.004 by 0.05 you will get 0.08 as the quotient.

Answer:
13 bags
Step-by-step explanation:
Area of the lawn: A=lw
w= 64 ft
P= 2(l+w)= 278 ft ⇒
bags of seed required:
- 4800/384= 12.5 so 13 full bags needed
A, D and E are correct
given ( x - 4 ) is a factor then x = 4 is a root
the remainder on division by (x - 4 ) = 0 as indicated by the 0 on the right side of the quotient
(x - 4 ) is a factor of 3x² - 13x + 4 → A
the number 4is a root of f(x) = 3x² - 13x + 4 → D ( explained above )
thus 3x² - 13x + 4 ÷ (x - 4 ) = 3x - 1 → E
the quotient line 3 - 1 0
3 and - 1 are the coefficients of the linear quotient and 0 is the remainder
