Pretend the stuff under it cannot be touched when adding or subtracting
so (square root of 15) + (square root of 15) =
2(square root of 15)

Answer:
c.
Step-by-step explanation:
Your answer should be C.
Explanation: answer B is to little of an amount so that is not the answer and $19 multiplied by 8hrs is only $152 so there for the answer cannot be answer b, because that is way over the max amount that can be made in 8 hrs and 3/4 is really 6 hours out of 8 hours. And 6 multiplied by $19 is $114 so your answer would be C.
Answer:
x = 5
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h is height )
Here A = 20, b = (x + 3) and h = (2x - 5) , then
(x + 3)(2x - 5) = 20 ← multiply both sides by 2
(x + 3)(2x - 5) = 40 ← expand left side using FOIL
2x² + x - 15 = 40 ( subtract 40 from both sides )
2x² + x - 55 = 0 ← in standard form
(x - 5)(2x + 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
2x + 11 = 0 ⇒ 2x = - 11 ⇒ x = - 5.5
But x > 0 , so x = 5
