The program is an illustration of loops
<h3>What are loops?</h3>
Loops are program statements that are used to perform repetition
<h3>The main program</h3>
The program written in Python, where comments are used to explain each line is as follows:
#This initializes sum to 0
summ = 0
#This gets input for the first number
num = int(input())
#This is repeated while num is not -1
while num!= -1:
#This calculates the sum
summ+=num
#This gets input for the num
num = int(input())
#This prints the sum
print(summ)

Answer:
Step-by-step explanation:
Yep you are 100% correct grate job!!
137 - 16X = Y
Since Lorraine is picking blackberries in her backyard at a rate of 15 berries per minute, and after 16 minutes of picking, there are still 137 blackberries left to pick, to determine an equation that models how many berries are left (y) after x minutes of picking, the following calculation must be performed:
137 - 16X = Y
Thus, for example, after 5 minutes the calculation would be as follows:
- 137 - 16 x 5 = Y
- 137 - 80 = Y
- 57 = Y

<h2>2(x - 5)(x + 3)</h2>
Step-by-step explanation:
![2x^2-4x-30\\\\=2\cdot x^2-2\cdot2x-2\cdot15\\\\=2(x^2-2x-15)\\\\=2(x^2+3x-5x-15)\\\\=2[x(x+3)-5(x+3)]\\\\=2(x+3)(x-5)](https://tex.z-dn.net/?f=2x%5E2-4x-30%5C%5C%5C%5C%3D2%5Ccdot%20x%5E2-2%5Ccdot2x-2%5Ccdot15%5C%5C%5C%5C%3D2%28x%5E2-2x-15%29%5C%5C%5C%5C%3D2%28x%5E2%2B3x-5x-15%29%5C%5C%5C%5C%3D2%5Bx%28x%2B3%29-5%28x%2B3%29%5D%5C%5C%5C%5C%3D2%28x%2B3%29%28x-5%29)
