The length of a rectangle is represented by (2x2−5x+5)cm and the width is represented by (x2+4x−3)cm. What is the representation

Katarina [22]

Answer: $6x^2-2x+4$

Step-by-step explanation:

Given

The length of a rectangle is given by

$l=2x^2-5x+5$

and the breadth is given by

$w=x^2+4x-3$

Perimeter is the sum of the sides of rectangle

$\therefore \text{Perimeter P= }2(2x^2-5x+5+x^2+4x-3)\\\Rightarrow P=2(3x^2-5x+4x+5-3)\\\Rightarrow P=2(3x^2-x+2)\\\Rightarrow P=6x^2-2x+4$

Thus, the perimeter is given by $6x^2-2x+4$ .

Rewrite the following expression as a single logarithm. Which letter is the correct answer?

Pepsi [2]

Answer: OPTION B

Step-by-step explanation:

You need to remember the logarithms properties:

$log(a)+log(b)=log(ab)\\\\log(a)-log(b)=log(\frac{a}{b})\\\\log(a)^b=blog(a)$

Then, you can rewrite the expression as a single logarithm:

$log(x+3)^2+log(x-7)^3-log(x-2)^5-log(x^2)\\\\log((x+3)^2(x-7)^3)-log(\frac{(x-2)}{(x^2)})\\\\log(\frac{(x+3)^2(x-7)^3}{x^2(x-2)^5})$

This matches with the option B.
