Answer:
x = 5±2√7
Step-by-step explanation:
This quadratic cannot be factorised via the factorisation method, so we use the quadratic formula :
x = 
or x = 
(The reason I did 2 equations is because brainliest does not allow me to do the ± in the equation insert thing )
x = 
or x = 
x = 
or x= 
x = 
or x = 
x = 
or x = 
Hope this helped and brainliest please
5 times 12=x times 4
switch sides- x times 4= 5 times 12
x times 4=60
x times 4 60
-------------- = ------
4 4
x=15
Hope this helps!! Feel free to thanks me, rate me 5/5 and make me brainliest!!
Answer:
12n -5 ≤ 55
Step-by-step explanation:
12 times a number (represented by n) is 12n.
"Decreased by 5" means 5 is subtracted from the product, giving 12n-5.
"Is no more than 55" means "is less than or equal to 55".
Then the expression written using math symbols is ...
12n -5 ≤ 55
I believe it is B. y = 2x + 2
I think to solve it you need to add them togeter (sorry I’m in 3rd grade so if I’m wrong then my bad)
