5 cups of flour will make 5/(1 1/2) x 15 = 50 shortbread cookies
4 cups of sugar will make 4/(1 1/4) x 15 = 48 shortbread cookies
1 3/4 cups of butter will make (1 3/4)/(1/2) x 15 = 52 1/2 shortbread cookies
Therefore, 5 cups of flour, 4 cups of sugar, and 1 3/4 cups of butter will make 48 shortbread cookies.

In decimal form the answer is 20.34375
Answer:
Step-by-step explanation:
circle A is
x²+y²+6x-4y-12=0
x²+6x +y²-4y =12
think (a+b)² = a²+2ab+b² we have a=x, b= 3
and (a-b)² = a²-2ab+b² so we have a=y, b=2
x²+6x +9 +y²-4y+4 = 12-9-4
(x+3)² +(y-2)²= -1
compare to the general equation of a circle (x-h)²+(y-k)² =r²
the center is at (-3,2) and the radius is √-1 =i
Circle B has center (0, -4) and radius 3 so the equation is
(x-0)²+(y-(-4))² =3²
x² +(y+4)² = 9
point (√8, -3) is on the circle if it verifies the equation
√8² +(-3+4)² = 9
8+1 =9 true so the point is on the circle
Circle A and circle B are not similar because they do not have the same center and radius
