The sum of -19ab and 7ab = -19ab + 7ab = -12ab
the sum of -11ab and -23ab = -11ab + (-23ab) = - 34ab
So
<span>Subtract the sum of -11ab and -23ab from the sum of -19ab and 7ab:
</span> (-12ab) - (-34ab) = -12ab + 34ab = 22ab
Answer
22ab
multiply 12 and 16 then multiply 8 and 10 then add them up to get 15,360
It’s 18
If they have to be equal, every vase has to have a yellow flower therefore if you had 1 yellow flower and 1 white flower (the lowest possible equal combination) then you can only have 18 groups otherwise you would have an equal number in each case
F(x) = x² - 10x - 24 , 24= (-12)*2 and -12+2 =-10
f(x) = (x-12)(x+2)
Answer A. f(x) = (x-12)(x+2)
