i only know that answer is 3
I think u will need to add 5ml acid into the solution to get 25% acid
Answer:
135
Step-by-step explanation:
Use formula b(h) which is 9x15 and get 135
First we will compute the h+k and then multiply the result by 2.
To add polynomials, we add terms whose variables are alike, for example:
we add the coefficients of x^2 together, the coefficients of x together and so on.
Therefore:
h + k = x^2 + 1 + x - 2 = x^2+x-1
Now, we will multiply this answer by 2 to get the final answer:
2(h+k) = 2(x^2+x-1) = 2x^2 + 2x -2
Diameter is 2r, or 18.8 ft
Circumference is 2*pi*r, or 59.1 ft
