1/4 + 1/2 ..you cant directly add them as they are unlike fractions ..so to add then first convert them into like fractions ...for that find the LCM of the denominators ..2 and 4 ..
LCM of 2 and 4 is .. 4 
so 1/4 + 1/2 will become 1/4 + 2/4 ...(because we multiplied 1/2 with 2 to make denominator as 4)

=> the answer is 3/4 ..

this is how i do ..

Hope it helps !!!

Find the value of the expression. 7! ÷ 3! 5,040 5,034 840 24
koban [17]
First, let's review what the "factorial operator"  !   means.

5! = 5*4*3*2*1.

3! = 3*2*1

7! = 7*6*5*4*3*2*1

Then:  

 7!         7*6*5*4*3*2*1       7*6*5*4         5040
----- = ----------------------- = ------------- = ----------- = 5040 (answer) 
 3!              3*2*1                     1                  1

The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.​
mars1129 [50]

Answer:

The area of the rectangle in terms of 'x' = 13x

Step-by-step explanation:

  • Perimeter = 30 cm
  • Length = x cm

Using the perimeter formula to find the width w.

P=2(l+w)

P = 2l + 2w

2w = P-2l

Dividing both sides by 2

w\:=\:\frac{P}{2}-2

as P = 30 cm

w\:=\:\frac{30}{2}-2

w\:=\:15-2

w = 13 cm

Using the formula of the rectangle area

A = wl

substitute w = 13 and l = x in the formula

A=13\times \:x

A = 13x

Therefore, the area of the rectangle in terms of 'x' = 13x
