The answer to your question is 9 x 9 = 81.
Sry just add a triangle on each side took that test
So since you know that x^2-1 is equal to (x-1)(x+1),
you can figure that this factors to
(y^2-x^3)(y^2+x^3)
because you know how the difference of two squares formula, stated on the top line of this answer.
Answer:
Find the value of x(attachment 11)
6)
7x = 6 + 5x
7x - 5x = 6
2x = 6
x = 6/2 = 3
7)
30 = 4x + 6
4x = 30 - 6 = 24
x = 24/4 = 6
8)
2(x + 4) =16
x + 4 = 16/2 = 8
x = 8 - 4 = 4
9)
7 + 5x = 3x + 13
5x - 3x = 13 - 7
2x = 6
x = 6
<u>Find the area(From attachment 2)</u>
1) Area = 4* 5 = 20
2)Area = 7 * m = 7m
3). Area = 3* a = 3a
4). Area = x*x = x²
5). Area = 4*x + 3* 4 = 4x + 12
6). Area = 7*a + 7*9 = 7a + 63
7). Area = 3x*x + 2*3x = 3x² + 6x
<u>expression of line segment</u>
8) x + 9
9). x + 4
10). a + 2
