Answer:
Step-by-step explanation:
The pH of solution a decreases, as the pH of solution B decreases as well.
It is C.
First, you have to do the problem in the (), so 3*4 = (12). 12 - 2 is 10. Next, you do the other () which is 5 + 7 which is 12. 12 + 10 = 22
The area of the square in terms of x unit is x²/ 2
<h3>Diagonal of a square</h3>
The expression for the diagonal of a square is written as'
d^2=s^2+s^2
Where
- s² is the area of the square
- d² is the diagonal of the same square
But from the given question we have that the diagonal of the said square is 'x'
Now, let's substitute the values into the expression of the diagonal given above,
d^2=s^2+s^2
d² = s² + s²
We have,
x² = s² + s²
Collect and add like terms
x² = 2s²
But we know that s² represents the area of the square
So,
x² = 2 × area
Make 'area' subject of formula
Area = x²/ 2
Now, we can say that the area of the square in terms of x units is x²/2
Therefore, the area of the square in terms of x unit is x²/ 2

Plug in 1.5 for x, to start off. It is then simplified to : 3*(1.5)* y - 5y
Then plug in -3 for y, it's then simplified to : 3*(1.5)* -3 - 5 * (-3)
First, multiply 1.5 times 3, and that will get you 4.5. The multiply 4.5 with -3, and that will get you -13.5. Moving on, subtract -13.5 from the 5 that is being multiplied to -3, which is -15. In conclusion, -13.5 subtracted from -15 would be -28.5. Hope this helps!

The first rectangle would have a perimeter of 25(2)+2(2) = 54 inches.
The second rectangle would have a perimeter of 20(2)+5(2)=50 inches.
The third rectangle would have a perimeter of 17(2)+8(2)=50 inches.
The fourth rectangle would have a perimeter of 15(2)+5(2)=40 inches.
The fifth rectangle would have a perimeter of 15(2)+10(2)=50 inches.
