Answer: perfect square trinomials

Step-by-step explanation:

Although you don't provide the 4 multiple choice answers, here they are:

a) perfect square monomials

b) difference of terms

c) perfect square trinomials

d) difference of perfect squares

The answer is c) perfect square trinomials, for a perfect square trinomial is a trinomial that can be factored into a binomial multiplied to itself.

In the scenario of a perfect square trinomial, there will be 2 terms that'll be perfect squares. For example, in the trinomial x2 - 12x + 36, both x2 and 36 are perfect squares.

In this case, it is a special product formula because there's a specific formula for them — unlike the other answers.

algol [13]

Given the area, to rewrite the function using distributive property we get:
6(2x+5y)
using distributive property we open the parenthesis, this will give us:
6×2x+6×5y
simplifying the above we get
=12x+30y

Answer: 12x+30y

Maya has 3 times as many dimes as nickels. She has 4 more quarters than nickels. if she has a total of $9.40, how many of each t

puteri [66]

Answer: nickels = 14, dimes = 42, quarters = 18

Step-by-step explanation:

Let n represent nickels which has a value of $0.05

Let d represent dimes which has a value of $0.10

Let q represent quarters which has a value of $0.25

It is given that:

n = n

d = 3n

q = n + 4

and their total value is $9.40 ⇒ n + d + q = $9.40

Use substitution to find the quantity of nickels:

.05(n) + .10(3n) + .25(n + 4) = 9.40

5n + 10(3n) + 25(n+4) = 940 multiplied by 100

5n + 30n + 25n + 100 = 940 distributed

60n + 100 = 940 added like terms

60n = 840 subtracted 100

n = 14 divided by 60

n = 14

d = 3n

= 3(14)

= 42

q = n + 4

= (14) + 4

= 18

Answer:

h(x)=-x-1

let y =-x-1

interchanging role of x & y

x=-y-1

y=-x-1

h-¹(x)=-x-1

again

f(x)=(2-3x)/2

let

y=(2-3x)/2

interchanging role of x & y

x=(2-3y)/2

2x-2=-3y

y=(2-2x)/3

f-¹(x)=(2-2x)/3

Given function are not inverse of each other.

10.

f(x)=-x+3

let y=-x+3

interchanging role of x & y

x=-y+3

y=3-x

f-¹(x)=-x+3

equal to g(x)=-x+3
