The cost of large pizza is $24.62, a small pizza has an 8-in. diameter a large pizza has a 15-in. diameter the pizzeria charges the same price per square inch for both pizzas and the small pizza cost $7.
Step-by-step explanation:
The given is,
A small pizza has an 8-inches in diameter
A large pizza has a 15-inches in Diameter
The small pizza cost $7
Step:1
Area of smaller pizza,
...................................(1)
Where, r - Radius of small pizza
From given, 

r = 4 inches
Equation (1),

( ∵
=3.14 )
Square inches
Step:2
Area of smaller pizza,
...................................(1)
Where, r - Radius of small pizza
From given, 

r = 7.5 inches
Equation (1),

( ∵
=3.14 )
Square inches
Step:3
Cost of pizza per square meter,


= $ 0.1393 per square meter
× 

= $24.62
Result:
The cost of large pizza is $24.62, a small pizza has an 8-in. diameter a large pizza has a 15-in. diameter the pizzeria charges the same price per square inch for both pizzas and the small pizza cost $7.
119 I believe since a straight angle sums up to 180
2 nuumbers multiply to 8 an addd to 6
factor 8 and add teh factor pairs
1,8
2,4
8+1=9
2+4=6
numbers are 2 and 4
if you were to solve it the
xy=8
x+y=6
y=6-x
x(6-x)=8
6x-x^2=0
0=x^2-6x+8
facotr
0=(x-2)(x-4)
set each to zero
x-2=0
x=2
x-4=0
x=4
x=2 or 4 and since they are interchangable, the numbes are 2 and 4
x = 10
