Answer: x = 10

Step-by-step explanation: First, you combine like terms. Your equation is now 5x-2 = 48. Then, you isolate the variable by moving the -2 onto the other side. Now your equation is 5x = 50. Then you divide 5x by 5 to isolate x and divide 50 by 5 and get 10, so x = 10.

If 32x+1 -3x+5, what is the value of x?
kozerog [31]

Answer:

x=-0.21...

Step-by-step explanation:

Make the expression equal 0

32x+1-3x+5=0

Combine the x terms

29x+1+5=0

Combine the constants

29x+6=0

Isolate the x term

29x=-6

Isolate the variable

x=-0.21...

(I rounded to the nearest 100th)

Answer:

36i^{2}+48i+16

Step-by-step explanation:

(4+6i)^{2} is essentially (4+6i)(4+6i) (you are squaring (4+6i), so multiplying it by itself), so to simplify, you would need to distribute.

A good way to go about this is using the F.O.I.L. method, multiplying the First numbers in the parentheses, then the Outers, then Inners, and finally, Lasts.

(4+6i)(4+6i) >> (4+6i)(4+6i) >> (4+6i)(4+6i) >> (4+6i)(4+6i)

((4*4)+(4*6i)+(6i*4)(6i*6i))

After doing so, you would end up with 16+24i+24i+36i^{2}, and after combining like terms, 16+48i+36i^{2}.

To write the expression in standard form, though, just order the terms from highest to lowest power!
