Answer:
q1: yes
q2: no
Step-by-step explanation:
2(5)+10(1)=20
10+10=20
20=20
(5)+(1)=6
5+1=6
6=6
(8)=(1)+3
8=1+3
8=4
The given expression is :
2xx+3-5(x-2)
We know that, 

Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
Answer:
-64
Step-by-step explanation:
The question is asking to solve 
Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.
is the same as -4 · -4 · -4
First let's figure out if this will be negative or positive
Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive
Now find out what 4 x 4 x 4 equals (64)
In conclusion the answer is -64
