Answer:
Square pizza
Step-by-step explanation:
To obtain which pizza is the best buy:
Cost of square pizza :
AED 80
side length, s = 26cm
Area of square, A = s²
A = 26² = 676 cm²
1 AED of square pizza gives : 676 / 80 = 8.45 cm²
Cost of circular pizza :
AED 80
Radius, r = 28cm
Area of circle, A = πr²
A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²
1 AED of circular pizza gives : 616 / 80 = 7.7cm²
Hence, square pizza is the better buy ;
8.45cm² > 7.70 cm²

Answer:
-8, -7
Step-by-step explanation:
f(x)=x^2+15x+56
0 =x^2+15x+56
What two numbers multiply together to make 56 and add together to 15
7*8 = 56
7+8=15
0 = (x+8) (x+7)
Then use the zero product property
x+8 =0 x+7 =0
x+8-8 =0-8 x+7-7 =0-7
x=-8 x=-7
