Answer:
![\text{Smaller square's 15 inches, Bigger square's 18 inches}](https://tex.z-dn.net/?f=%5Ctext%7BSmaller%20square%27s%2015%20inches%2C%20Bigger%20square%27s%2018%20inches%7D)
Step-by-step explanation:
GIVEN: The length of each side of a square is
inches more than the length of each side of a small square. The sum of the areas of the square is
inches.
TO FIND: the lengths of the sides of the two squares.
SOLUTION:
let the length of side of small square be ![\text{x}](https://tex.z-dn.net/?f=%5Ctext%7Bx%7D)
Area of small square ![=(\text{side})^2=\text{x}^2](https://tex.z-dn.net/?f=%3D%28%5Ctext%7Bside%7D%29%5E2%3D%5Ctext%7Bx%7D%5E2)
As length of each side of bigger square is
more than the smaller square
length of side of bigger square ![=\text{x}+3\text{ inches}](https://tex.z-dn.net/?f=%3D%5Ctext%7Bx%7D%2B3%5Ctext%7B%20inches%7D)
Area of bigger square ![=(\text{x+3})^2](https://tex.z-dn.net/?f=%3D%28%5Ctext%7Bx%2B3%7D%29%5E2)
Also
Sum of areas of both square ![=549\text{ inch}^2](https://tex.z-dn.net/?f=%3D549%5Ctext%7B%20inch%7D%5E2)
![(\text{x})^2+(\text{x+3})^2=549](https://tex.z-dn.net/?f=%28%5Ctext%7Bx%7D%29%5E2%2B%28%5Ctext%7Bx%2B3%7D%29%5E2%3D549)
![2\text{x}^2+6\text{x}+9=549](https://tex.z-dn.net/?f=2%5Ctext%7Bx%7D%5E2%2B6%5Ctext%7Bx%7D%2B9%3D549)
![\text{x}^2+3\text{x}-270=0](https://tex.z-dn.net/?f=%5Ctext%7Bx%7D%5E2%2B3%5Ctext%7Bx%7D-270%3D0)
![\text{x}=15,-18](https://tex.z-dn.net/?f=%5Ctext%7Bx%7D%3D15%2C-18)
as the length of side can never be negative
![\text{x}=15](https://tex.z-dn.net/?f=%5Ctext%7Bx%7D%3D15)
length of side of smaller square ![=15\text{ inches}](https://tex.z-dn.net/?f=%3D15%5Ctext%7B%20inches%7D)
length of side of bigger square ![=\text{x}+3\text{ inches}](https://tex.z-dn.net/?f=%3D%5Ctext%7Bx%7D%2B3%5Ctext%7B%20inches%7D)
![=18\text{ inches}](https://tex.z-dn.net/?f=%3D18%5Ctext%7B%20inches%7D)
Hence the length of smaller and bigger square are
and
respectively.
Answer:
Ok, so we have the fact that plus +minus=minus
Thats the fact. It always works that way that same signs means positive and different means negative, as explained with logic.
4+(-5)
So we know that 4 is positive and -5 is negative
if you look at it through a number line, substracting 5 from 4 you have
3--->2---->1---->0---->-1
Under zero, the negatives start, so its proved by maths and logic as well.
Step-by-step explanation:
points: (1, 4), (2, 8), (3, 12), and (4, 16)
Step-by-step explanation:
just follow the table and plot the points
I think it talks about if this is a one to one function or not
$20×.25=$5
$20-$5=$15
$15×.15=$2.25
$15+$2.25=$17.25
$17.25 is your answer
