x^2 = -25

there is a solution if you know imaginary numbers

if you do not stop now and say no solution

else

take the square root

x = sqrt (-25)

x =sqrt(-1) sqrt(25)

x=+- 5i

x = 5i, -5i


x^2 =18

take the square root of each side

x =+-sqrt(18)

x=+- sqrt(9)sqrt(2)

x=+- 3sqrt(2)

x=3sqrt(2), -3sqrt(2)

DedPeter [7]

Answer:

A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636

as a fraction it would be 36/99, divide both numbers by 9 to get 4/11

B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666

as a fraction that would be 33/90 , divide both by 3 to get 11/30

C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Rewrite using the distributive property and GCF 16 + 40
Artist 52 [7]

The GCF of 16 and 40 is 8.

16/8 = 2

40/8 = 5

We can rewrite this using the distribute property like so:

<h3><u>8(2 + 5)</u></h3>

Using the distributive property:

16 + 40

16 + 40 = 56

We can also add inside the parentheses and multiply and we'll get the same answer.

8(7)

56
