Answer:
625m
Step-by-step explanation:
The area is equal to l times w, so since the length and width are the same value you would do 25 x 25 which gets you to 625
Answer:
12 g of water she use.
Step-by-step explanation:
Given : Jen wants to make 60% salt solution using 18g of salt.
To find : How much water should she use.
Solution : Let x be the solution.
So, 60% of x is 18 g.
∴
Which means Total solution is 30 g and 18 g is the salt
So, quantity of water = 30-18 = 12g
Hello from MrBillDoesMath!
Answer:
31a. 2 real roots
31b 2 complex roots
Discussion:
31a.
2x^2 + 3x - 6 = 0
Using standard quadratic notation, the above equation has a = 2, b = 3 and c = -6. The discriminant is given by b^2 - 4ac, which is
3^2 - 4*2*(-6) = 9 + 48 = 57 > 0, so the quadratic has 2 real roots
31b.
The equation is equivalent to 16x^2 + 10x +3 = 0. Its discriminant is
10^2 - 4 * (16) * (3) = 100 - 192 = -92 so this equation has two complex roots
