155 is your answer lmk if you need anything else
The last terms must multiply to the last terms (confusing)
example
if ax^3+bx^2+c+d=(ex+f)(gx+h)(jx+k) then
d=fhk
so
70 is last term
we got 2 and 5
2*5*?=70
10*?=70
divide by 10
?=7
the missing number is 7
About 7.5 miles if you divide 45/3 is 15 so divide 15/2 which is 7.5
A= bh(1/2)
a=12(14)(1/2)
a= 168(1/2)
a= 84inches
Your answer: A=50cm²<span><span>Base: 5cmHeight: 20cm</span></span>A=hbb2=20·52=50cm²
