Split the triangle in half and use the Pythagorean theorem:

x = sqrt(13^2 - 5^2)

x = sqrt(169 - 25)

x = sqrt(144)

x = 12

The answer is D. 12

If cost of 12 pens is ₹134, then what will be the cost of 5 such pen( please explain by method, don't answer directly)

sertanlavr [38]

First you need to divide ₹134 by 12 to find the cost of each pen.

$\frac{134}{12} = \frac{67}{6}$

Multiply the cost of each pen by 5 to find the cost of 5 pens.

$( \frac{67}{6} ) \times 5 = \frac{335}{6}$

≈ ₹55.8 (correct to 1 decimal place)

A parallelogram has an area of x2 + 9x - 36.

malfutka [58]

Answer:

Step-by-step explanation:

Please use " ^ " to indicate exponentiation:

A = x^2 + 9x - 36. This factors into A = (x + 12)(x - 3). We can assume that the length of the parallelogram is x + 12 and that the width is x - 3.

Note that if x = 3 the area becomes zero. So: x must be greater than 3, so that the (x - 3) factor is positive.

Example: If x = 4, then the dimensions of the parallelogram are 4 + 12, or 16, and 4 - 3, or 1.
