Step-by-step explanation:
we multiply 8.6*24 and get 206.4
we know this because 1 gallon is equal to 8.6 so we multiply both quantities and get 206.4
×3-13 ×4-14 ×5-15 ×6-16
1. vertical angles
2. Adjacent angles
3. Supplementary angles
or, 2x-x^2+2x^2=1
or,2x+x^2=1
or,x^2+2x-1=0
or,x^2+x+x-1=0
or,x(x+1)+1(x-1)=0
or,(x+1)(x-1)=0
therefore x=(-1,+1)
