Answer:
A) 23cm.
B) 32.0625 square cm.
Step-by-step explanation:
<u>Perimeter:</u> Just add all the sides together like so:
4.75x2 + 6.75x2 = 23cm.
<u>Area:</u> Multiply the base and height together:
4.75 x 6.75 = 32.0625 square cm.
The smallest of two integers is 61
Step-by-step explanation:
Let x be the smaller integer
Then the next integer will be:
x+1
According to given statement that the sum of both is 123
![x+ (x+1) = 123\\x+x+1=123\\2x+1=123](https://tex.z-dn.net/?f=x%2B%20%28x%2B1%29%20%3D%20123%5C%5Cx%2Bx%2B1%3D123%5C%5C2x%2B1%3D123)
Subtracting 1 from both sides
![2x+1-1=123-1\\2x=122](https://tex.z-dn.net/?f=2x%2B1-1%3D123-1%5C%5C2x%3D122)
Dividing both sides by 2
![\frac{2x}{2}=\frac{122}{2}\\x=61](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B122%7D%7B2%7D%5C%5Cx%3D61)
The smallest of two integers is 61

-x - y = -5
y = x + 1
-x -(x + 1) = -5
-x - x - 1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2
y = x + 1
y = 2 + 1
y = 3
solution is : (2,3)
