Answer:
y = 2x² + 16x + 11
I hope im right... If not reaaally sorry!!
B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12
g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56
b= 56 + 12
b= 68
In triangle ABC and DEF
AC =DF, [ given ]
AB =DE, [ given ]
angle A = angle D
by SAS
ABC congruent to triangle DFE
so
BC = EF, [ CPCTC]
hence proved
