A fluid ounce is a customary unit for measuring liquid capacity.
Answer:
Step-by-step explanation:
The equation is:
√b+20 - √b = 5
The first step is we will add √b to both sides:
√b+20 -√b +√b = 5 +√b
√b+20 = 5+√b
Now take square at both sides:
(√b+20)^2 = (5+√b)^2
b+20 = 25+10√b+b
Now combine the like terms:
b+20-25-b=10√b
-5 = 10√b
Divide both the terms by 10
-5/10 = 10√b/10
-1/2=√b
Take square at both sides:
(-1/2)^2 = (√b)^2
1/4 = b
So in this type of question we add radical terms to both sides and square both sides twice....
x would equal 2 because:
4 times 5 is 20
4 times 2x is -8x
move over the 8x to the side with the 2x
then you have 10x=20
20/10 equals x=2
Hope this helps :)
Answer: I believe it is c?
Answer:
50
Step-by-step explanation:
5(-2)^2 + 3(10)
