Answer:
125
Step-by-step explanation:
Area of trapezoid = 
Bases = 11 and 14
(11+14)=25
25/2=12.5
12.5 x 10 = 125
Answer:
x + 4 - 3√2 and x + 4 + 3√2
Step-by-step explanation:
When other methods seem to difficult to apply, try using the quadratic formula:
Here a = 1/2, b = 4 and c = -1.
Then the "discriminant" is b^2 - 4ac, or
(4)^2 - 4(1/2)(-1), or 16 + 2 = 18
Then the roots are:
-4 ± √18, or -4 ± 3√2
and thus the factors are x + 4 - 3√2 and x + 4 + 3√2
x = ---------------------
Answer:
x=1
Step-by-step explanation:
Since the four is negative, you'd add four to both sides. Negative three plus four is positive 1. Therefore x equals one.
x+-4=-3
+4 +4
x=1
