Answer:
Step-by-step explanation:
3.2x10^10
-11x10^10

answer = 14.2
<em>(2a - 3x - 3y)(2a + 3x + 3y)</em>
- Step-by-step explanation:
<em>Hi there !</em>
use formula
<em>a</em><em>² - </em><em>b</em><em>² = (a - b)(a + b)</em>
<em>a</em><em> = 2a</em>
<em>b</em><em> = 3(x + y)</em>
<em />
<em>4a² - 9(x+y)² =</em>
<em>= [2a - 3(x + y)][2a + 3(x + y)]</em>
<em>= (2a - 3x - 3y)(2a + 3x + 3y)</em>
<em />
<em>Good luck !</em>
Multiply the y by 4 then the -6 by 4
4f - 24
-3/8 divided by -1/3
Do the reciprocal of -1/3 and change the division sign to a multiplication sign.
-3/8 x -3/1
Multiply the numerators and denominators
-3 X -3 = 9
8 X 1 = 8
As an improper fraction, it is 9/8.
As a mixed number it s 1 1/8
