A square has all 4 sides the same.
When given the area of a square , you can find the length of the side by finding the square root of the area:
Side length = √215
Side Length = 14.6628
Rounding to the nearest 0.05 would = 14.65 feet.
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225

Step-by-step explanation:
Answer:
11) 67%; 12) 25%
Step-by-step explanation:
Problem 11: Find the fraction representing 30 out of a total of 45, and then multiply the result by 100%:
30/45 = 2/3 = 0.67; then we see that 30 is 67% of 45.
Problem 12: Same method:
16/64 = 1/4 = 0.25. Mult. this by 100%: 16 is 25% of 64.
