The total cost of working out at the local gym is made up of a membership fee and a cost per visit. The current membership fee is $20 and it costs $2.50 per visit. If the
cost per visit is reduced to $2, write an expression for the new total cost if the cost
for 10 visits remains the same.

b). 4320 have a nice day

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

the answer is -1 for this question

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
