Select all the expressions that are equivalent to –8. A. 80/100
B. -800/100
C. 80 ÷ (-10)
D. -80 ÷ (-10)
E. –80 - (–10)

B and c

Step-by-step explanation:

Hey there.

a)80/100=8/10=4/5=0.8 so a is not equivalent

b)-800/100=-8 so b is equivalent

c)80/(-10)=-8 so c is equivalent

d)-80/-10=8 so d is not equivalent

e) -80-(-10)=-80+10=-70 so is not equivalent

Therefore I believe B and C are equivalent.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

a negative exponent is translated as follows:

so, we have
