Jackets cost $15 and a set of decorative buttons cost $5. The delivery fee is $5 per order. The expression 15n+5n+5 gives the cost, in dollars, of buying jackets with buttons for n people. Write this expression after combining like terms. *

20n + 5

Step-by-step explanation:

From the question, we are told that jackets cost $15 and a set of decorative buttons cost $5 and that the delivery fee is $5 per order.

The expression 15n+5n+5 gives the cost, of buying jackets with buttons for n people. The expression after combining like terms would be:

= 15n + 5n + 5

= 20n + 5

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
