Answer:
3.88025 x
Step-by-step explanation:
139, I am sorry if I'm wrong
a1=11; d=19-11=8
a17=11+(17-1)*8=11+128=139
B. 4x + 1
4x^2 + 21x + 5
= (4x + 1)(x + 5)
Factors of this trinomial are (4x + 1) and (x + 5)
Answer
(4x + 1)
24 cm
8+8=16
4+4=8
8+16=24 cm
*Perimeter includes adding all sides, area is multiplying all sides.
