Answer:
c) 144
Step-by-step explanation:
Since A is between Y and Z,


however, the question asks for
, not the value of x.
Thus,

× 

Answer:
x = 7
Step-by-step explanation:
Because:
GD = x + 4
GC = 4x + 5
And D is the centroid of ABC
So GC = 3GD
<=> 4x + 5 = 3(x + 4)
<=> 4x + 5 = 3x + 12
<=> 4x - 3x = -5 + 12
<=> x = 7
Done!!
You ok?? :))
Answer: 432 units²
Step-by-step explanation:
The figure is composed by two trapezoids.
The formula for calculate the area of a trapezoid is:

Where "B" is the larger base, "b" is the smaller base and "h" is the height.
Let be
the area of the figure,
the area of the trapezoid on the left and
the area of the trapezoid of the right. Then the area of the figure will be:


Substituting values, you get:

Answer:
Step-by-step explanation:
If the area of a triangle is 150cm^2, the formula would look like:
150=0.5b*h
So, if we were to solve for the base in terms of h, we'd simply divide both sides by 0.5b getting:
(150)/(0.5b)=h
which simplifies to
h=300b
