<span>We write the equation in the standard form which is:
ax^2 + bx + c = 0
(x + 15)(x) = 100
x^2 + 15x - 100 = 0
(x + 20) (x-5) = 0
The solutions are
x = -20 and x = 5
Therefore, the correct answer is option B. </span><span>The solution x = 5 should be kept, but x = –20 is unreasonable.</span><span>

7(a+3) this is the answer im pretty sure
Answer:
(y+4) /2
Step-by-step explanation:
(y²-16)/(2y+6) × (y+3)/(y-4) =
(y+4)(y-4) / 2(y+3) × (y+3)/(y-4)
=> eliminate all (y-4) and (y+3)
so, we get :
(y+4)/2
Answer:
![p=4.8n](https://tex.z-dn.net/?f=p%3D4.8n)
Step-by-step explanation:
Price for each sandwiches = $4.80
Number of sandwiches ordered = ![n](https://tex.z-dn.net/?f=n)
Total price charged by deli = ![p=4.8n](https://tex.z-dn.net/?f=p%3D4.8n)
Answer:
(2.4)(-1.8) and (0.6)(-0.4)
Step-by-step explanation:
The product of two negative numbers = a positive number. (negative × negative = positive).
Product of two positive numbers = a positive number. (Positive × positive = positive)
Product of a negative number and a positive number = a negative number. (Negative × positive = negative).
Therefore, the answer choice that shows two products that both will result in negative values would be the answer choice that has a negative number multiplying a positive number.
Option 3 has two products in which each has a negative and positive number. That is (2.4)(-1.8) = a negative value, and
(0.6)(-0.4) = a negative value.
Therefore, the answer is Option 3: (2.4)(-1.8) and (0.6)(-0.4)
