Evaluating polynomials is sometimes easier if they are put into "Horner form."
= ((-5x +3)x -8)x +2
= ((-5(-2) +3)(-2) -8)(-2) +2 . . . . use -2 for x
= (13(-2) -8)(-2) +2
= (-34)(-2) +2
= 68 +2 = 70
The value of the expression when x = -2 is 70.
Answer:
The formula to determine the length of rectangle with perimeter and width is L =
Step-by-step explanation:
Given as :
The perimeter of rectangle = P
The length of rectangle = L
The width of rectangle = W
∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width
I.e P = 2 L + 2 W
Or, 2 L = P - 2 W
∴ L =
Hence The formula to determine the length of rectangle with perimeter and width is L = Answer
Answer:
Brand one offers a lower price per pound.
Step-by-step explanation:
We have been given that a conversation store sells 1/3 pound of one brand of tail mix for 1.50 and 1/2 of another brand of trail mix for 2.15. We are asked to find the brand which offers lower price per pound.
First of all, we will find price of per pound trail mix for each brand.
Since 1/3 pound of one brand of tail mix costs $1.50, so the cost of one pound trail mix would be 3 times $1.50 that is .
Since 1/2 pound of other brand of tail mix costs $2.15, so the cost of one pound trail mix would be 2 times $2.15 that is .
Since $4.30 is less than $4.50, therefore, brand one offers a lower price per pound.
