Find the area and perimeter of this figure

1 answer:

5 0

In order to accomplish that assignment, you might suspect that a person
needs to know something about the figure ... things like maybe what shape
it is, and what a few of its measurements are. You would be absolutely correct
too. I've looked over your question, and found that you haven't included a single
shred of information about the figure. I don't know if it's a square that can fit in
the bottom of my coffee cup, or a circle that the Earth can fit through. If I see it
walking around on the street tomorrow, I won't even recognize it. Although I do
crave to solve the problem and answer your question, I have nothing to get to
Square-1 with. I'm sitting here at Square-0 , looking for information to use in
my calculations.

So, the problem is asking for one of the equations to be rewritten. Lets rewrite the second one. The way to create a system of equations that will cancel is to create a situation where the a or b of both equations add to 0. In this case, we can multiply the second equation by 3 to turn the 3y into 9y.

$3(-x + 3y) = (6)3$

$-3x + 9y = 18$

Our new system is $4x - 9y =9$ and $-3x + 9y = 18$ . We can now add these together.

$4x - 9y = 9$

$-3x + 9y = 18$

Adding each part straight down, we get the equation:

$x + 0 = 27$

We now have an equation with a single variable, which also tells us that x is equal to 27.

Extra: To find the value of y after this, we merely need to plug in the value of x to one of the equations and solve for y.

$-27 + 3y = 6$

$3y = 33$

$y = 11$

What is - 15 + n < - 8

Norma-Jean [14]

-15 + n < -8
Add 15 to both sides
-15 + n + 15 < -8 + 15
Then simplify,
n < 7

Answer:

1/(72x^11)

Step-by-step explanation:

Multiply like terms and according to rules of exponenets, add exponents which are multiplied. If you have a negative exponent, then put the reciporical of it and you end up with 1/(72x^11).
