Answer:
3(x + 1)(3 - x).
Step-by-step explanation:
(x + 3)^2 - 4x^2
Using the identity a^2 - b^2 = (a - b)(a + b), we have
(x + 3 - 2x)(x + 3 + 2x)
= (-x + 3)(3x + 3)
= 3(x + 1)(3 - x)
Answer:
-90 , 30
Step-by-step explanation:
sina = cos(2a)
= 1 - 2(sina)^2
2(sina)^2 + sina -- 1 = 0
( sina + 1 )( 2sina - 1 ) = 0
sina = -1 or sina = 1/2
=> a = -90 degrees or => a = 30 degrees
Answer: <b is 59.3 degrees
Step-by-step explanation:
Triangles have total of 180 degrees
The bottom two points are both 4y
To solve: 4y+4y+(3y+14)=180
11y+14=180
-14
11y=166
Divide by 11
Y=15.1
So plug that in for y
3(15.1)+14=B
59.3
