Step-by-step explanation:
....... wont let me type the name of the app so I'm gonna code it with the numbers of the alphabets.
13 1 20 8 23 1 25 is a really good one
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12
hope this helps !
First your going to distribute the 3
3(-3x+15)
-9x+45
27=6x-9x+15
27=-3x+15
Then you’ll minus 15 from 27
27-15=12
12=3x
X=4
Answer:
Step-by-step explanation:
As we can see in the image below, the number of tiles that form the word HI!, is ; this represents the or the total.
Now, if we count the number of tiles in H, this number will be . So, we have to find what percent this number represents by a Rule of Three:
If:
----
----
Then:
This is the percent of tiles in H.
5/9 times 3/4 = 5/12
Hope this helps!
