The ratio given is 4:5 so you do 5divided by 20 which is 4 and multiply 4 and 4 and get 16 so your ratio is 16:20
For perpendicular lines, the slopes are negative reciprocals of one another. Therefore, the slope of QC = 3/2
Using this into the formula of slope:
3/2 = (y + 6) / (-1 + 3)
y = -9
If the slope of CD is 2/3, then y works out to be -3.
the answer is D x= x 5 because it make sense
<span> C(12,0)C(10,4)+C(12,1)C(10,3)+C(12,2)C(10,2) =
(1)(210)+(12)(120)+(66)(45) = 210+1440+2904 = 4554

4x^2 because it’s to the second degree unlike the others which are to the first degree.
