After lunch, hailey goes to the pet store. suppose hailey buys 5 guinea pigs at 20% off the original price of g dollars per guinea pig, which expression will not give hailey's total cost?
a) 4g
b) 5g
c) 5g − 0.2(5g)
d) 5g − 1g

Option B

The expression 5g will NOT give Hailey's total cost

Solution:

Given that Hailey buys 5 guinea pigs at 20% off the original price of g dollars per guinea pig

From given information,

Number of guinea pigs bought = 5

Original price = g dollars

Given that Hailey has bought 5 guinea pigs at 20% off

Price at which hailey bought pigs after offer is given as:

price per guinea pig after offer = g - 20 % of g

Total cost for 5 guinea pigs:

Total cost = 5(g - 20% of g)

The above expression can be written in different ways:

or

or

Thus Option A, Option C, Option D are correct

So Option B will NOT give Hailey's total cost

idk this answer sorry cant on this one.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
