4 0

Answer:

no

Step-by-step explanation:

3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense

x=  3 is a solution

and id you don't understand the first thing i said watch this

#1. 3, - 4

#2. x= - 4

#3. substitute/replace the x with what the x coordinate is

#4. it will be 3= - 4

#5. as you can see the numbers don't equal each other so it's a no solution

(5x+1)(5x-1) combine terms
Alinara [238K]

Answer:

25x^2 -1

Step-by-step explanation:

If you multiply parentheses:

(5x*5x) + (5x*-1) + (1*5x) + (1*-1)

25x^2 - 5x + 5x -1

25x^2 -1

A simpler way is to memorize this formula

(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)

What is the value of X​
skad [1K]

Answer:

X = -3

Step-by-step explanation:

Multiply both sides by 3

3x 1/3(3) = -3(3)

3x/3 = -9/3

divide both sides by 3 to isolate x

x = -3
