Answer:
the equation is : x²-x-12
Step-by-step explanation:
the quadratic equation is in the form of : y=ax²+bx+c
the product of the zeros is -12 and the sum is 1
b = - 1
c=-12 (product)
y=x²-x-12
check : factorize first (x+3)(x-4)=0
either x+3=0 then x=-3
or x-4=0 then x=4
-3*4=-12
-3+4=1
the equation is : x²-x-12

Answer:
x-intercept= 12
y-intercept=-4
Step-by-step explanation:
Let's write this proportion of equivalent ratios in equation form and then plug in our two known values to determine our two unknown values:
(s1)2 : (s2)2 = A1 : A2
(10)2 : (7)2 = 100 : 49
Ratio of the Areas = 100 : 49
