A triangle has side lengths of ( 4h + 2k) centimeters, (9h + 4m) centimeters, and (2m - k) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

Answers

Answer 1

Answer:

P = (13h+k+6m) cm

Step-by-step explanation:

Given that,

The side lengths of a triangle are :

(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm

We need to find the perimeter of the triangle.

We know that,

Perimeter = sum of all sides

So,

P = (4h + 2k)+(9h + 4m)+(2m - k)

= (4h+9h)+(2k-k)+(4m+2m)

= 13h+k+6m

Hence, the perimeter of the triangle is (13h+k+6m) cm.

Write an algebraic expression to represent the phrase:

Twenty five less than the quotient of a number and six.

Answers

Answer: n/6 - 25

Step-by-step explanation:

We can use the vairiable n to represent the unknown number.

Because the question asks ofr the quotient of n and six, we can write the term as n/6

Because the question also asks for 25 less then that term, we can write the whole statement as: n/6 - 25 .

Therefore, the algebraic expression to represent the phrase Twenty-five less than the quotient of a number and six is n/6 - 25.

Hope this helps and good luck! :D

What is the price of the items Nakita bought?
20 Nakita bought items at a grocery store
she bought 2 boxes of crackers for $3.50 each
she used a coupon for $0.80 off the price of each box of crackers
she bought a jar of peanut butter for $4.85.
she bought a package of juice boxes for $2.40.
she used a coupon for $3.00 off the total price of the items she bought
This expression can be used to determine the price of the items Nakita bought
[2(3.50 - 0.80) + 4.85 + 2.401 - 3.00
A $6.95
B $10.45
C $9.65
D $12.65

Answers

Answer:

B $10.45

Step-by-step explanation:

Fist you find how much the 2 boxes of cracker cost

$3.50 * 2 = $7

Then subtract the amount of 2 crackers by the $0.80 coupon

$7 - $0.80 = $6.20

Then add that amount to the cost of a jar of peanut butter

$6.20 + $4.85 = $11.05

Then add that about for with the amount of a package of juice boxes

$11.05 + $2.40 = $13.45

Then subtract the total amount to the $3.00 coupon

$13.45 - $3.00 = $10.45

B $10.45 is your answer

Given f(x)=4x+5 and g(x)= x^2+x; find (f∘g)(-5)
Please show all steps thank you

Answers

Answer:

[tex](f\circ g)(-5)=85[/tex]

Step-by-step explanation:

We are given:

[tex]\displaystyle f(x)=4x+5\text{ and } g(x)=x^2+x[/tex]

And we want to find:

[tex](f\circ g)(-5)[/tex]

This is equivalent to:

[tex]\displaystyle =f(g(-5))[/tex]

So, we will evaluate g(-5) first, which yields:

[tex]\displaystyle g(-5)=(-5)^2+(-5)=25-5=20[/tex]

So:

[tex]=f(g(-5))=f(20)[/tex]

Then:

[tex]\displaystyle f(20)=4(20)+5=80+5=85[/tex]

Therefore:

[tex](f\circ g)(-5)=85[/tex]
