For this case we must find the value of the variable "x" of the following expression:
![2 (3x-1) \geq4x-6](https://tex.z-dn.net/?f=2%20%283x-1%29%20%5Cgeq4x-6)
We apply distributive property to the terms within parentheses: ![6x-2 \geq4x-6](https://tex.z-dn.net/?f=6x-2%20%5Cgeq4x-6)
We subtract 4x on both sides:
![6x-4x-2 \geq-6\\2x-2 \geq-6](https://tex.z-dn.net/?f=6x-4x-2%20%5Cgeq-6%5C%5C2x-2%20%5Cgeq-6)
We add 2 to both sides:
![2x \geq-6 + 2\\2x \geq-4](https://tex.z-dn.net/?f=2x%20%5Cgeq-6%20%2B%202%5C%5C2x%20%5Cgeq-4)
We divide between 2 on both sides:
![x \geq \frac {-4} {2}\\x \geq-2](https://tex.z-dn.net/?f=x%20%5Cgeq%20%5Cfrac%20%7B-4%7D%20%7B2%7D%5C%5Cx%20%5Cgeq-2)
Answer:
![x \geq-2](https://tex.z-dn.net/?f=x%20%5Cgeq-2)
Answer:
The answer is: ![3x^2-14x+7](https://tex.z-dn.net/?f=3x%5E2-14x%2B7)
which agrees with answer B) among your list of possible options.
Step-by-step explanation:
I think you forgot an "x" in the first trinomial, so, let's try that:
![(5x^2-5x+1)-(2x^2+9x-6)=\\= 5x^2-5x+1-2x^2-9x+6=\\=3x^2-14x+7](https://tex.z-dn.net/?f=%285x%5E2-5x%2B1%29-%282x%5E2%2B9x-6%29%3D%5C%5C%3D%205x%5E2-5x%2B1-2x%5E2-9x%2B6%3D%5C%5C%3D3x%5E2-14x%2B7)
Answer:
253cm²
Step-by-step explanation:
Area of the trapezoid = 1/2(b1+b2)*h
Given
h = 22cm
b1 = 10.5cm
b2 = 12.5cm
Substitute
Area of the trapezoid = 1/2(10.5+12.5)*22
Area of the trapezoid = 1/2(23)*22
Area of the trapezoid =11*23
Area of the trapezoid = 253cm²
Hence the area of the trapezoid is 253cm²
The answer should be... -14.4. :)
