Answer:
B
Step-by-step explanation:
(f+g)(x)=f(x)+g(x)
3x+1+x2-6 = x2+3x-5
Step-by-step explanation:
118 is the answer 238-120 = 118
x = the length of one piece
y = the length of the other piece
the total length is 100 cm this means
x + y = 100
one piece is 16 inches longer than the other
first we need to convert inches to cm:
1 in = 2.54 cm
16 in = 2.54*16 = 40.64
now we can write
x = y + 40.64
by solving the system of equations
x + y = 100
x = y + 40.64
we find
x = 70.32 cm
y = 29.68 cm
the lengths of the two pieces are 70.32 cm and 29.68 cm.
