Answer:
A plane extends infinitely in two dimensions. It has no thickness. An example of a plane is a coordinate plane. A plane is named by three points in the plane that are not on the same line.
Step-by-step explanation:
Answer:
80 Degrees
Step-by-step explanation:
just flip and overlap the figure (in your mind)
Answer:
(3)(-16)(-7)(-14) = (-48)(-7)(-14) = (+336)(-14) = - 4704;

Answer:
Step-by-step explanation:
A) Use the distributive property to eliminate parentheses. Then combine like terms. (The only "like terms" are the constants.)
... = 12 +3·2y +3·(-3) . . . use the distributive property to multiply each term in parentheses by the factor 3 outside those parentheses
... = 12 +6y -9 . . . . . . . . simplify
... = 6y + (12 -9) . . . . . . group like terms together
... = 6y + 3 . . . . . . . . . . simplify
___
B) Look for factors of each term that are also found in the other term.
... 18b has factors 3×6×b
... 12 has factors 2×6
The only common factor is 6, so we factor that out using the distributive property.
... 18b -12 = 6(3b -2)

<em>Comment on factoring</em>
For factoring problems, it helps immensely if you know your times tables and some of the rules for divisibility. (Even numbers are divisible by 2, numbers ending in 0 or 5 are divisible by 5, numbers whose sum of digits is divisible by 3 are divisible by 3, for example.)
Answer:
144 ft^2
Step-by-step explanation:
It is the same as the area of a single triangle with a base of 18 ft and a height of 16 ft. The formula is ...
A = (1/2)bh
= (1/2)(18 ft)(16 ft) = 144 ft^2
The shaded area is 144 ft^2.
