12
Step-by-step explanation:
6+6=12
Answer: Second option.
Step-by-step explanation:
By definition, a Quadrilateral is a flat shape that has four straight sides.
A Rectangle is a Quadrilateral and has the following properties:
1. Its Opposite sides have the same length.
2. All its angles have equal measure (They are congruent).
3. Each one of those angles measure 90 degrees (An angle with this measure is also known as "Right angle").
4. Its opposite sides are parallel.
5. Its opposite sides have equal lenght.
In this case you can observe that the figure defined by the points E, F, G, and H has four sides, four right angles and its opposite sides are parallel and have equal length.
Therefore, based on the above, you can conclude that it is a Rectangle.
Answer:
<h2>135 ft²</h2><h2 />
Step-by-step explanation:
see attached image
<u>shaded area = total area (1) - unshaded triangular area (2)</u>
1. area of a trapezoid = (a + b) * h/2
where a = 8, b = 18, h = 15
Area of trapezoid = (8 + 18) * 15/2 = 195 ft²
2. Area of unshaded triangle = 1/2 (8) 15 = 60 ft²
shaded area = 195 - 60 = 135 ft²
Answer:
8x³ - 25x² - 3x + 18
Step-by-step explanation:
(2x + 3)(4x²- 5x + 6)
multiply 2x by each of the three terms in the second expression to get:
8x³ - 10x² + 12x
now multiply 3 by each of the three terms in the second expression to get:
12x² - 15x + 18
Combine 'like terms': -10x² + (-15x²) = -25x²
Combine 'like terms': 12x + (-15x) = -3x
Put all terms in decreasing exponent order:
8x³ - 25x² - 3x + 18
