3400
Step-by-step explanation:
70×60=4200
10+20=30
70-30=40
40×20=800
4200-800=3400
The synthetic division is not same as the polynomial long division.
Given:
Let's take a polynomial function f(x) = divided by x-2.
Using synthetic divison:
2 1 2 -5 -6
0 2 8 6
1 4 3 0
(x-2)(x^2+4x+3)
= (x-2)(x+3)(x+1)
Polynomial long division:
x-2) (x^2+4x+3
x^3- 2x^2
4x^2 - 5x + 6
4x^2 - 8x
3x + 6
3x - 6
0
=(x-2)(x^2+4x+3)

27 and 3/8 rounds down to 27.
- 1 and 1/10 rounds up to - 1
We are estimating the difference which tells us to subtract so 27 - (- 1) = 27 + 1 = 28
Your estimate for this equation is 28.
no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor
Because both 100 and 140 share a common factor of 20
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio
