Answer:
"Take the square root of both sides of the equation"
A is correct
Step-by-step explanation:
We are given quadratic equation
We need to solve for x. We have to isolate x here.
Here square on x. So, first we get rid of square.
Taking square root both sides to get rid of square.
For example:
a2=25
sqare a2 = +- sqare 25
x2=9/16 to solve for x
sqare x2 +- sqre 9725
x=+- 3/5
Hence, "Take the square root of both sides of the equation"
Answer:
7x-7+8x9=23
Step-by-step explanation:
7x-7+8x9=23
Answer:
x = 111°
Step-by-step explanation:
We know that angles in a triangle add up to 180°
Step 1: Find angle supplementary to <em>x</em>
82 + 29 + x = 180
111 + x = 180
x = 69°
Step 2: Find angle <em>x</em>
Both the angles are supplementary, meaning they add up to 180°.
x + 69 = 180
x = 111°
Answer:
Step-by-step explanation:
The equation is given to be : -6 + 4x = 8
Now, we need to solve this equation in order to find the value of x
⇒ -6 + 4x = 8
Adding +6 on both the sides
⇒ -6 + 4x + 6 = 8 + 6
⇒ 4x = 14
dividing each term by 4
Answer:
6*5*4*3*2*1+4*3*2*1-3*2*1 =
6*5*4*3*2*1+(4-1)*3*2*1=
6*5*4*3*2*1+3*3*2*1=
3*2*1*(6*5*4+3)
this number has more than 2 factors, therefore is composite
