What are the solution(s) to the quadratic equation 50 – x2 = 0? A. x = +2V5
B. x = +63
C. x = +5V2
D. no real solution
Please help hurry :/

±5 sqrt(2) =x

Step-by-step explanation:

50 – x^2 = 0

Add x^2 to each side

50 = x^2

Take the square root of each side

±sqrt(50) = sqrt(x^2)

±sqrt(25*2) = x

±sqrt(25)sqrt(2)=x

±5 sqrt(2) =x

If you have to choose an alternative, it is C. is one of the solutions/roots of the quadratic equation, but the correct answer is actually .

Step-by-step explanation:

Once

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
