=> 2-63-16
=>(-61) - 16
=> -77
b.64 / 4+(3*4)
=> 64 / 4+12
=> 64 / 16
=> 4
c. 3x+2(x-7)
=> 3x+2x - 14
=> 5x-14
d. 5 + 6^2/ 4
=> 5+ 36/4

Answer:
20x?
Step-by-step explanation:
The answer would be 5.457
A = 5x − 1 and B = 2x
A + B = 5x - 1 + 2x
= 7x - 1
A − B = 5x - 1 - 2x
= 3x - 1
A • B = (5x - 1) *2x
= 10x2 + (-2x)
all 3 are polynominals
so Mariana is correct.
