Simplify the expression. write your answer as a complex number. 2 times the square root of 25 plus the square root of negative 16 10 + 4i 10 − 4i 10 + 8i 10 − 8i

10 + 4i  

Step-by-step explanation:

A.

Step-by-step explanation:

We are asked to simplify the given expression .

We will use imaginary unit 'i' to solve our given problem.

Write 25 as square of 5:

Substitute in the expression:

Write 16 as square of 4:

Therefore, the simplified form of our given expression would be .

1/5

step-by-step explanation:

the dice has 6 sides and there is only one 5 in a dice.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
