Explanation

Number of pens produced in February = 3000 - 10% Number of pens produced in February = 3000 - 30= 2700 pens Number of pens produced in March is 2700 - 10% of 2700 Number of pens produced in March = 2700 - 270=2430 pens

Explanation

.The square root of 1.44 can be written as (1.44)1/2. So

(1.44)1/2 = (1.2 × 1.2)1/2

(1.44)1/2 = [(1.2)2]1/2

(1.44)1/2 = (1.2)2/2

(1.44)1/2 = (1.2)1

Thus,

√1.44 = 1.2

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Subtract 216 from 616: 616 - 216 = 400

Add 216 to 400: 400 + 216 = 616

So, the correct answer is 616.

Explanation

10+10=20

Explanation

Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.

For example, 3x+2x-5 is a polynomial.

Explanation

Greater than or equal to is represented by the symbol    "≥".

Explanation

Let the number x, added 3, then doubled the sum = 40 

40 - 6 = 34 

34 divided by 2 = 17
