Evaluate the polynomial for x=-4

The answer is

Step-by-step explanation:

4x² + 5 - 6x³ + 3x⁴ - x

x = - 4

Substitute the value of x into the expression

That's

4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4

Simplify

4(16) + 5 - 6( -64) + 3( 256) + 4

64 + 5 + 384 + 768 + 4

We have the final answer as

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
