Answer:
x = √(28), or x = 5.292
Step-by-step explanation:
First you distribute the square to the values inside of the parentheses. so it ends up looking like this
5(x^2 - 25) - 9 = 6
add 9 to both sides
so its 5(x^2 - 25) = 15
Then distribute the multiplication of 5 to the contents within the parentheses
so it would be 5x^2 - 125 = 15
add 125 to both sides
you get 5x^2 = 140
divide by 5 on both sides
you get x^2=28
then, take the square root of both sides to reverse the square
√(x^2)=√(28)
and in the end you get x=5.292
but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
Answer:
I don't get it
Step-by-step explanation:
you need to clarify so that i can searched it
Answer:
since the denominators are the same we add 3 and 7 in the numerator to get 10/8 or 1 2/8, and we can simplify to 5/4 or 1 1/4.
Hope this helps and brainliest please
Answer:
To factor something out you've got to divide, so you would take 5x+40 and divide it all by 5
So, 5x/5= 1x
And, 40/5= 8
Your answer is now x+8 when factored
