You would do 11ft x 6.5 then that would equal 71.5. Then do 6 x 5 which is 30 then add them up so it equals 101.5
Find two numbers that multiply to -30 (last term) and add to 7 (middle coefficient)
The two numbers are 10 and -3
10 times -3 = -30
10 plus -3 = 7
Using those two values gets us the two factors (y+10) and (y-3)
Therefore, y^2+7y-30 factors to (y+10)(y-3)
The equation y^2+7y-30 = (y+10)(y-3) is true for all values of y.
Answer: 45 mph
Step-by-step explanation:
We know that Rob was driving 63 mph which is 18 miles faster than pigeons, therefore you subtract to get the answer.
63-18=45
