X=8 is the correct answer :)
Answer: Choice B)
The points A, C and D form a triangle which is the front face you see in the pyramid. Point F is not on this triangle at all. Point F is towards the back at the base of the pyramid away from this front face. So we consider A,C,D,F collectively as a whole to be not coplanar. If we ignored the point F, then we can say that A,C,D are coplanar.
x greater than negative 2, because ln(x) is undefined for x <= 0 (-2+2=0, -1.999...+2>0)
Answer:
x+1
x+5
Step-by-step explanation:
- x^2 + 6x + 5=
- x^2 +x + 5x + 5 =
- x(x+1) + 5(x+1) =
- (x+1)(x+5)
Factors are:
Answer:
12 units²
Step-by-step explanation:
a=longer base
b = shorter base
h = height
Area=(a+b)*h/2
Area = (10+2)*2/2=12 units²
