Answer:
x = 3/2
Step-by-step explanation:
(2x + 3)2 – 4(2x + 3) - 12 = 0
Simplify the equation then isolate for x.
Distribute over brackets:
(4x + 6) – (8x + 12) - 12 = 0
Combine like terms:
4x + 6 – 8x + 12 - 12 = 0
6 - 4x = 0
Isolate x:
6 = 4x
6/4 = x
Reduce the fraction:
6/4 = x <= divide top and bottom by "scale factor" of 2
3/2 = x
x = 3/2 <= having x on the left side is standard
35% was damaged.
1 percent is 400 acres, so 14000/400= 35% of forest was burned
Answer: The expression, 8 x 54, may also be expressed as 8 x 50 + 8 x 4 because by factoring the 8,
8 x (50 + 4) = 8 x 54
Further, it can also be expressed as,
8 x 60 - 8 x 6
because,
8 x (60 - 6) = 8 x 54
Step-by-step explanation:
The graph of a non member's yearly cost is steeper, and also has a lower y-intercept. And the graph of a member's yearly cost starts higher, but is less steep.
Answer:
-1
Explanation:
3π / 4 = (3*180) / 4 = 135 degrees
Since 135 is in the 2nd quadrant, therefore:
tan (135) = - tan (45) = -1
cot θ = 1/tanθ
Therefore:
cot (3π / 4) = 1/tan(3π / 4)
cot(3π / 4) = -1
Hope this helps :)
