Also, C) 436 in² is correct :)
Step-by-step explanation:
the answer is C
if we take the 15 from 28
13 will be left
so 13×22=286
and 15×5=75
15×5=75
150+286=436
hopefully its helpful
D. x = 7 and x = 14
this is a quadratic equation, so use the quadratic formula: (-b+-√b^2-4ac) / 2a for ax^2+bx+c=0
a = 3, b = 5, c = 1
plug into quadratic formula
f(X) 70x49
