What are the answer choices??
Answer:
undefined
Step-by-step explanation:
The square root of a negative number is undefined
Let h be the price of a hamburger, d be the price of a hot dog and c be the price of a cheeseburger
3+d=h —(1)
c-20=h —(2)
3h=2d+2c-75 —(3)
Sub (1), (2) into (3)
3h=2(h-3) + 2(h+20) -75
3h =2h-6+2h+40-75
3h=4h-41
h=41
Therefore, the price of a hamburger is $41
Answer:
its answer will be 9.first by using phythagorus theorem h^2=p^2+b^2'then h=15,p=12and b=x. again by putting the values of h ,p and b we get ,(15)^2=(12)^2+x^2. 225=144+x^2, x^2=225-144, x^2=81,x=√81,x=9 answer
Move the constant to the left, use the quadratic formula, remove the parentheses, evaluate calculate, separate the solutions. The equation has 2 solutions
