Answer:
The dimensions of constant C are of ![[L^{3}T]^{-4}](https://tex.z-dn.net/?f=%5BL%5E%7B3%7DT%5D%5E%7B-4%7D)
Step-by-step explanation:
It is given that
Since the dimensions of volume are ![[L^{3}]](https://tex.z-dn.net/?f=%5BL%5E%7B3%7D%5D)
Each of the term shall have a dimension of since they are in addition.
Thus for third term we can write
Thus we have
![[L^{3}]=[C][T^{4}]\\\\\therefore [C]=[L^{3}][T^{-4}]](https://tex.z-dn.net/?f=%5BL%5E%7B3%7D%5D%3D%5BC%5D%5BT%5E%7B4%7D%5D%5C%5C%5C%5C%5Ctherefore%20%5BC%5D%3D%5BL%5E%7B3%7D%5D%5BT%5E%7B-4%7D%5D)
Since 75% = 3/4
then $15 = 3/4 of the original price
Divide 15 ÷ 3 to get the 25% of the original price
(1/4 of the price)
15 ÷ 3 = 5
$5 is the 25% of the original price
so, if 25% + 75% = 100%
then $5 + $15 = $20
The original price for the sweaters was $20.

6(x+5)² + 5(x+5)-4 = 0
(x+5)(x+5) = x(x+5)+5(x+5) = x² + 5x + 5x + 25 = x² + 10x + 25
6(x²+10x+25) + 5(x+5) - 4 = 0
6x² + 60x + 150 + 5x + 25 - 4 = 0
6x² + 60x + 5x + 150 + 25 - 4 = 0
6x² + 65x + 171 = 0

Answer:
A. -41/15.
Step-by-step explanation:
15x^2 + 23x - 41 = 0
Product of the roots of ax^2 + bx + c = c/a.
Thus the product of the roots of this equation = -41/15.
