Three different equations that have x=5 as a solution

Mathematics
1 answer:
gulaghasi [49]3 years ago
4 0

Answer:

The easiest ways to do this is to add, subtract, multiply, or devide 5 from a number, do that operation to x, and set that number as the equivelent.

For example

3 * 5=15

so

3x=15

Is this correct please explain
uysha [10]

Answer:

79°

Step-by-step explanation:

since this figure goes around completely, the sum would be 360°

1 and 3 are equal, so you would multiply 101 by 2

101 × 2 = 202

subtract 202 from 360

360 - 202 = 158

4 and 2 are equal, so divide 158 by 2

158 ÷ 2 = 79

so angle 4 = 79°

Complete the following exercises by applying polynomial identities to complex numbers.
erik [133]

1.)

   =(x-8i)(x+8i)

x^2+8ix-8ix-64i^2

x^2-64i^2

x^2-64(-1)

x^2+64

2.)

    =(4x-7i)(4x+7i)

16x^2+28ix-28ix-49i^2

16x^2-49i^2

16x^2-49(-1)

16x^2+49

3.)

    =(x+9i)(x+9i)

x^2+9ix+9ix+81i^2

x^2+18ix+81(-1)

x^2+18ix-81

4.)

    =(x-2i)(x-2i)

x^2-2ix-2ix+4i^2

x^2-4ix+4(-1)

x^2-4ix-4

5.)

    =[x+(3+5i)]^2

(x+5i+3)^2

(x+5i+3)(x+5i+3)

x^2+5ix+3x+5ix+25i^2+15i+3x+15i+9

x^2+6x+10ix+30i+25i^2+9

x^2+6x+10ix+30i+25(-1)+9

x^2+6x+10ix+30i-25+9

x^2+6x+10ix+30i-16

Hope this helps :)
