Answer:
EF = 44 ft
Step-by-step explanation:
Given that ABCD is congruent to EFGH, it follows that their corresponding lengths and angles would be congruent to each other.
This means, for the sides:
AB = EF,
BC = FG,
CD = GH
AD = EH.
Therefore, if AB = 44 ft, corresponding side, EF = 44 ft
Answer:
p-q= -4
p=q-4
x^2 + px + q=0
=> x^2 + (q-4)x + q = 0
d= b^2-4ac
=(q-4)^2 - 4(1)(q)
= q^2 + 16 -8q - 4q
=q^2 -12q+16
given that D=16
q^2 -12q+16 = 16
=> q^2 -12q = 0
=> q^2 = 12q
=> q = 12q/q
=> q= 12
Therefore the value of q is 12 and the value of p is q-4 = 12-4= 8
