Describe a situation in which opposite quantities combine to make 0.
Hello!
Answer: A real life example would be if you would add 100 dollars in a bank account and then, subtract the 100 dollars from that account.
The equation used would be 100 + (-100) or in a simpler version 100 - 100 (They both mean the same thing!)

A golfer hit a ball 230 m from the tee to the
green. The ball traveled south and landed on the
green in 4 seconds. What was the ball's speed?
Answer:
The ball's speed is 57.5 m/s
Step-by-step explanation:
Given;
distance between the tee and the green, d = 230 m
time taken for the ball to travel from the tee to the green, t = 4 seconds
The speed of the ball is given as;
speed = total distance traveled / total time taken
speed = 230 m / 4 s
speed = 57.5 m/s
Therefore, the ball's speed is 57.5 m/s

A map is drawn using a scale of 1 centimeter to 25 kilometers.
What actual distance is represented by a map length of 3.2 centimeters?
Enter the correct answer in the box.
Answer:
3.2 cm on map represents 80 kilometers of actual distance.
Step-by-step explanation:
It is given that the scale is:
1 cm = 25 km
And we have to find the distance that will be represented by 3.2 centimeters of length on the map.
Let x be the number of kilometers represented by 3.2 cm
[tex]\frac{1}{25} = \frac{3.2}{x}\\x = 3.2 * 25\\x = 80[/tex]
Hence,
3.2 cm on map represents 80 kilometers of actual distance.

Find the value of c that makes x^2+20x+c a perfect square trinomial. And then write expression as the square of a binomial.
The value of the variable 'c' is 10. Then the perfect square trinomial is (x + 10)².
What is a perfect square trinomial?A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.
The trinomial is given below.
⇒ x² + 20x + c
The value of 'c' must be equal to half of the square of the coefficient of x. Then we have
c = [1/2 × (20)]²
c = (10)²
c = 100
Then the perfect square trinomial is written as,
x² + 20x + 100 = (x + 10)²
The value of the variable 'c' is 10. Then the perfect square trinomial is (x + 10)².
More about the perfect square trinomial link is given below.
