We can solve for the equivalent expression of the given expression:
√(x+6) + √x = 8
First, we need to square both sides such as shown below:
((√x+6) + (√x) =8)²
(x+6) + x = 64
Perform transposition and combine similar terms
x + 6 + x =64
2x = 64 -6
x = 29
Answer:
$400
Step-by-step explanation:
To solve this, we need to understand how one reaches the final price. The general formula for final price (with tax) is:
t(c) = p x (1+t)
t(c) is total cost
p is price
t is tax rate as a decimal
To find p, we need to create a new formula. Since we have the total cost ($408) and the tax rate (2% or .02), we can divide the total cost by 1 + the tax rate to solve for the price:
t(c) / (1+t) = p
408 / (1+.02) = $400
I hope this helps!

8 quarters and 13 dimes
8 times 0.25 equalls 2.00
13 times 0.10 equalls 1.30
add 2.00 and 1.30
you get 3.30
8 plus 5 is 13
so there are five more dimes than quarters
Square root (8-0)^2 + (8+7)^2
square root 64+15^2
=8+15
= 23
The 4th one is the answer
