Answer:

  a≠0 and b≠0 and c≠0 and d≠0

Step-by-step explanation:

No denominator is allowed to be zero. 'c' and 'd' are in the denominator of the numerator and denominator terms. 'a' and 'b' are in the numerator of the denominator term, so will make that term zero if they are zero. In short, none of a, b, c, or d may be zero.

__

The fact that the expression simplifies to ...

  2acd^3/b

does not mean that the only restriction is b≠0.

If 2x+8=16, what is the value of x+4?​
True [87]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{8}}}}}

Step-by-step explanation:

<u>First</u><u>,</u><u> </u><u>finding </u><u>the </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u>

\sf{2x + 8 = 16}

Move 8 to right hand side and change it's sign

\dashrightarrow{ \sf{2x = 16 - 8}}

Subtract 8 from 16

\dashrightarrow{ \sf{2x = 8}}

Divide both sides by 2

\dashrightarrow{ \sf{ \frac{2x}{2}  =  \frac{8}{2} }}

Calculate

\dashrightarrow{ \sf{x = 4}}

Value of x is 4

<u>Now</u><u>,</u><u> </u><u>Substituting</u><u> </u><u>/</u><u> </u><u>Replacing </u><u>the</u><u> </u><u>value </u><u>of</u><u> </u><u>x</u><u> </u><u>in</u><u> </u><u>order</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>x</u><u>+</u><u>4</u>

<u>\sf{x + 4}</u>

plug the value of x

\dashrightarrow{ \sf{4 + 4}}

Add the numbers : 4 and 4

\dashrightarrow{ \sf{8}}

Hope I helped!

Best regards! :D

Given the following perfect square trinomial, find the missing term: ___x2 + 40x + 100 1 2 4 10
yuradex [85]

Answer:

4

Step-by-step explanation:

The correct option is 4.

Put 4 in the missing term because 4 is a perfect square and it satisfies the given expression:

4x2 + 40x + 100

Now multiply the 1st term coefficient with 100

4 *100 = 400

Now find two numbers whose product is 400 and whose sum is 40

20*20 = 400

20+20 = 40

Therefore 4 is the correct missing coefficient because it satisfies the expression:

Thus the correct option is 4....
