<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>
Answer:
3^10
Step-by-step explanation:
Because the rules of index
3^4 = 3*3*3*3
3^6 = 3*3*3*3*3*3
(3^4)(3^6)=
3*3*3*3*3*3*3*3*3*3 = 3^10
Ur answer is: -2a² + 7a + 1
The answer is A. 3° 87+90= 177+ 3= 180°
Answer:
x = -7
Step-by-step explanation:
Given parameters:
Slope of the line = 
Coordinates = (5,x) and (2,-3)
Unknown:
X= ?
Solution:
To find slope, use the expression below;
Slope =
y₂ = -3 y₁ = x
x₂ = 2 x₁ = 5
=
3(-3-x) = 4(-3)
-9 -3x = 12
-3x = 21
x = -7
