Answer:

(y^2+3y-28)/(4y^2-15y-4)

Step-by-step explanation:

(4y-1)(y-3)(2y+3)(y+3)(y+7)(y-3)/(2y+3)(y-4)(4y+1)(4y-1)(y-3)(y+3)

= (y+7)(y-3)/(y-4)(4y+1)

= (y^2+3y-28)/(4y^2-15y-4)

Answer:

(y+7)/(4y+1).

Step-by-step explanation:

If we factor  all the polynomials we get:

(4y-1)(y-3) .  (2y+3)(y+3) . (y-4)(y+7)

--------------    ----------------   -------------

(2y+3)(y-4)    (4y-1)(4y+1)   (y-3)(y+3)

we see that  (4y-1), (y -3), (2y+3), (y+3) and (y - 4)  are in the numerators and denominators so we can cancel them out.

This leaves us with:

(y + 7)

--------

(4y + 1)

2x(8+7)-6/2x(9-3) evaluate
Katarina [22]
Ok so assuming that the 'x' means multiply and not 'x' as in placeolder we do

PEMDAS
parenthaseees
exponents
multipilcation or division
additon or subtraction

parethasees simplify first
(8+7)=15


(9-3)=6

now we have
2x(15)-6/2x(6)
multiply
2x15=30

6/2x6=36/2=18

now we have
30-18

Aliun [14]
Corrine earns an hourly wage on top of her weekly gas allowance for her delivery job.

Her weekly earnings can be expressed as:

Earnings = 40 + 7.50h

When h=0, her earnings will be 40

This constant represents, the fixed gas allowance she is receiving for her delivery job. 7.50h represents that she get paid $7.50 for an hour of work. 

So, the constant term in the expression represent her weekly gas allowance.
