12 1/2 = 12.5
2.5mm = 2.5 cm
So the answer would be 15 cm
Answer:
19
Step-by-step explanation:
maximum no. of bag filled by 4275 sweets,is
4275/28 ~=152
therefore , there is 4256 sweets in 152 bags
therefore,4275-4256=19 sweets are left
Given:
Polynomial is
.
To find:
The sum of given polynomial and the square of the binomial (x-8) as a polynomial in standard form.
Solution:
The sum of given polynomial and the square of the binomial (x-8) is
![3x^2+15x-56+(x-8)^2](https://tex.z-dn.net/?f=3x%5E2%2B15x-56%2B%28x-8%29%5E2)
![[\because (a-b)^2=a^2-2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a-b%29%5E2%3Da%5E2-2ab%2Bb%5E2%5D)
![=3x^2+15x-56+x^2-16x+64](https://tex.z-dn.net/?f=%3D3x%5E2%2B15x-56%2Bx%5E2-16x%2B64)
On combining like terms, we get
![=(3x^2+x^2)+(15x-16x)+(-56+64)](https://tex.z-dn.net/?f=%3D%283x%5E2%2Bx%5E2%29%2B%2815x-16x%29%2B%28-56%2B64%29)
![=4x^2-x+8](https://tex.z-dn.net/?f=%3D4x%5E2-x%2B8)
Therefore, the sum of given polynomial and the square of the binomial (x-8) as a polynomial in standard form is
.
A)-28
B)-48
C)45
