The deli at the local grocery store sells chicken for $3.80 per pound, beef for $3.50 per pound, and salami for $2.90 per pound. Write an expression that shows how much it will cost to buy c pounds of​ chicken, b pounds of​ beef, and s pounds of salami.​ Write an expression that shows how much it will cost to buy c pounds of chicken, b pounds of beef and s pounds of salami

Then, find the cost for 1 pound of​ chicken, 1.8 pounds of​ beef, and 3.2 pounds of salami.
The cost of 1 pound of​ chicken, 1.8 pounds of​ beef, and 3.2 pounds of salami is ​$_

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

one that is bigger than 3 1/2

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

283 square feet

step-by-step explanation:

good luck
