I believe it’s A. Simplifying an expression.
Answer:
first answer is x= -5 second answer is y=7.
Step-by-step explanation:
7-5=2. 2+3=5.
7-1=6.
<span>y = 0.0000872x^3 - 0.00989x^2 + 0.403x + 1.192</span>
3x+12x=45
15x=45
x=3
the first chemical is 3*3 or 9 L
the second chemical is 12*3 = 36 L
Example
if ab=6
and a=3
b=2
a. 6 must be factor of 3 or 2 FALSE
b. 3 must be a factor of 3 OR 2 TRUE
c. 3 must be a factor of 3 AND 2 FALSE
B is true
