Answer:Then correct option is A
Step-by-step explanation:
The correct option is A
because 3^2+4^2=5^2 based on Pythagoras principle
2867.5 is bigger
Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first
If you ignore the decimal, your left with
290 vs 2867
2867 is much bigger than 290 so this is the answer
For
(c+d)(ex+f)
the expanded form is
dex^2+dex+cfx+df
(ce)x^2+(de+cf)x+(df)
ax^2+bx+c
the value of a is ce
the value of b is de+cf
the value of c is df
so
(-2x+3)(x+8)
(-2x+3)(1x+8)
b is 3*1+-2*8=3-16=-13
answer is -13
so pick 13 because we have -B, so B=13
