36 minutes.
(1/20)x+(1/30)x=1solve for x (x=0.8333333333......)
Considering they take the same times for all 3 pounds,
That would mean that since 1 pound takes 12 minutes, then 3 pounds take 36 minutes
B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.
The answer is C. Isosceles Triangle .... 2 of the sides are equal
The answer is -7 because :
a=1, b=1, c=2
Discriminant = b^2 - 4ac
= 1^2 - 4*1*2
= -7
Answer:

Step-by-step explanation:
From the graph, the x-intercepts are;



These are root of the polynomial function represented by the given graph.
By the remainder theorem;

According to the factor theorem, if
is a factor of
, then 
This implies that;
are factors of the required function.
Hence; 
We expand using difference of two squares to obtain;

We expand using the distributive property to get;

Rewrite in standard form to obtain;
