We are given :
Step 1: factor the part inside square root
The function given inside square root is of quadratic form.
So let us try to factorise it using AC method.
Here A*C = 4*25 = 100
so we have to find factors of 100 that add up to give -20.
the two factors are -10 and -10.
Rewriting the function :
=
=
=
Step 2:
Now we take square root of the factorised form
= 
Answer : (2x-5)
Answer:
A, x>3
Step-by-step explanation:
You solve the equation as normal by crossing out both sides and getting what equals to x, but since you divided by a negative the sign flips and you are left with your answer. Hope this helps!
Answer:
If 1 pint is equal to 2 cups, then 5 pints would equal _<u>5</u>_ cups.
Step-by-step explanation:
Let's use a ratio to solve:
pints : cups
1 : 2
2 : 4
3 : 6
4 : 8
5 : 10
There would be 10 cups in 5 pints.
46.8 is 39% of 120. Hope this helped you!
the first one is true and the second one is false
