How would you write an expression using a variable for the area and perimeter of a square with side 2x-9

Mathematics
1 answer:
Paladinen [302]3 years ago
7 0
Perimeter :
because there are four sides to a square and all sides are the same, the answer is 4(2x-9)
area:
area is basically length times width so the answer is (2x-9)(2x-9) or (2x-9)^2

If x+y=10 and x-y =6 what is the answer of x cube - y cube fast​
AfilCa [17]

Answer:

x+y=10 which means that x=10-y

Replace 10-y in the other equation which gives you:

10-y-y=6

10-2y=6

-2y=-4

y=2

Replace 2 in any of the 2 equations same answer for both:

x+y=10

x+2=10

x=8

So,

{x}^{3} - y^{3}

=  {8}^{3}  -  {2}^{3}

=512-8

=504

Hope this helps!

Ostrovityanka [42]

Answer:

44 / 2 = 22, 22 * 6 = 132, 132 + 3 = 135

Alternate method

45 * 3 = 135

Cassidy's goal is to raise more than $75 for charity. She has already raised $6. Now she is selling cupcakes for $3 each to reac
hodyreva [135]
$75= Cassidy's goal
c= number of cupcakes
a= $6 already raised

EQUATION:
75<$3c + a
substitute $6 in for a

75< $3c + 6
subtract 6 from both sides

69<3c
divide both sides by 3

23<c

Cassidy needs to sell at least 23 cupcakes to reach her goal of $75.


Answer:

FALSE: Cassidy will need to sell any number of cupcakes greater than 12 to reach her goal.

TRUE: Cassidy will need to sell any number of cupcakes greater than 23 to reach her goal.


Hope this helps!  :)
