In this problem, you are asked to solve the area of a
trapezoid. The formula in finding the area of a trapezoid is:
A = [(a + b)/2] x h
Where a = base 1
b = base
2
h =
height
Substituting the given measurements to the formula:
A = [(6.9 km + 2.7 km)/2] x 2.2 km
A = (9.6 km/2) x 2.2 km
A = 4.8 km x 2.2 km
A = 10.56 km^2
Therefore, the area is 10.56 square kilometers.
Answer:
x=-11
Step-by-step explanation:
Divide both sides by -7, and you get -11
Answer:
2,400 cm²
Step-by-step explanation:
You can solve for x because you know that 40cm=x²+4cm:
36 cm = x²
x = 6cm.
Therefore the width is 2(6)²-12, which is 60cm.
So the area is 40 cm x 60 cm, which is 2,400 cm².
Factor both the top and bottom.
(2(x-6)(x-2))/((x+6)(x-4))
To find zeros, the numerator must be 0. The denominator cannot be 0 because anything divided by 0 is infinity.
(x-6)=0
x=6
(x-2)=0
x=2
Final answer: x=2, x=6
The angle is in the third quadrant.
