Answer:
The opposite of 14 is -14.
Step-by-step explanation:
Opposites are numbers with the same distance from 0 but one is to the right of 0 and the other is to the left of 0.
The opposite of 0 is itself,0.
So the opposite of 5 is -5 since both 5 and -5 have the same distance from 0 and one is to the left and one is to the right of 0.
The opposite of 14 is -14 since both have the same distance from 0 and one is to the right and one is to the left of 0.
You can also think of this question as what can I add to 14 that will give me 0.
The answer is -14 since -14+14=0.
Another word for opposites is additive inverses. When you add additive inverses you get 0.
Another example: What is the opposite of -16?
The answer is 16 since 16+(-16)=0.
Answer:
14.2 cm
Step-by-step explanation:
A parallelogram is a quadrilateral (a four sided object) with parallel sides
Some of the characteristics of a parallelogram includes :
1. Opposite sides and angles are congruent .
2. Opposite angels are congruent
3. Consecutive angles are supplementary
4. The diagonals bisect each other
Area of a parallelogram = base x height
49.7 = 3.5 x height
height = 49.7 / 3.5 = 14.2 cm
Answer:
12). LM = 37.1 units
13). c = 4.6 mi
Step-by-step explanation:
12). LM² = 23² + 20² - 2(23)(20)cos(119)°
LM² = 529 + 400 - 920cos(119)°
LM² = 929 - 920cos(119)°
LM = 
= 
= 37.08
≈ 37.1 units
13). c² = 5.4² + 3.6² - 2(5.4)(3.6)cos(58)°
c² = 29.16 + 12.96 - 38.88cos(58)°
c² = 42.12 - 38.88cos(58)°
c = 
c = 
c = 4.6386
c ≈ 4.6 mi
-9 and 16 add to make 7 and multiply to make -144
