a= 16x+16
b= 40x + 15
Step-by-step explanation:
We know that perimeter of a rectangle is
![2(l + b)](https://tex.z-dn.net/?f=2%28l%20%2B%20b%29)
So therefore
![2(8x + 3 + 5) = a](https://tex.z-dn.net/?f=2%288x%20%2B%203%20%2B%205%29%20%3D%20a)
![= > 16x+ 6 + 10 = a](https://tex.z-dn.net/?f=%20%3D%20%20%3E%2016x%2B%206%20%2B%2010%20%3D%20a)
![= > 16x + 16 = a](https://tex.z-dn.net/?f=%20%3D%20%20%3E%2016x%20%2B%2016%20%3D%20a)
Answer= A) that is perimeter is 16x+16
We know that area of a rectangle is l×b
So therefore
![(8x + 3) \times 5](https://tex.z-dn.net/?f=%288x%20%2B%203%29%20%5Ctimes%205)
![= 40x + 15](https://tex.z-dn.net/?f=%20%3D%2040x%20%2B%2015)
Answer = b) that is area is 40x + 15
Answer:I got 33 and 34
Explanation:
Call your integers n and n+1 we get:
n+n+1= 67
rearrange:
2n = 66
n=66/2 = 33
The integers will be 33 and 34
Step-by-step explanation:
-2(x + 3) = 8
-2x - 6 = 8
-2x = 8 + 6
-2x = 14
x = -14/2
x = -7
