Answer:
The fourth option is the correct answer
Step-by-step explanation:
The given expression is
-2n(5+n-8-3n)
Given that n=3,We substitute the value of n into the expression and simplify.
This implies that,
-2n(5+n-8-3n)=-2(3)[5+3-8-3(3)]
=-6(5+3-8-9)
=-6(-9)
=54
Hence the answer is 54
Answer:
-12x^2 + 11xy - 2y^2
Step-by-step explanation:
Answer:
Malcolm would fill 8 bags of rice.
Step-by-step explanation:
The size of the container of rice = 5
pounds =
pounds.
Each bag of rice has a capacity of
pounds.
The number of bags of rice that Malcolm fills = 
=
÷ 
=
x 
= 
= 8
Therefore, Malcolm would be able to fill 8 bags of rice.
Answer
X1= 3-2 root3 x2= 1 x3=5 x4= 3 +2 root 3
First swap the sides then simplify the equation
Collect like terms
Move all the expression to the left to equal 0
Then collect like terms again
Reorder the terms from ^2 to ^4
Factor the expression
Change the signs
Separate into possible cases
Then sold the equation to equal 0
Then check solutions by subbing them in as x
Then you should have 4 perfect answers
