Please help me with this problem it's urgent:
3(x-5)^2=54

x = 3 sqrt(2) + 5 , x = -3 sqrt(2) + 5

Step-by-step explanation:

3(x - 5)^2 = 54

(x - 5) ^ 2 = 18

x - 5 = sqrt 18

x - 5 = 3 sqrt(2), -3 sqrt(2)

x = 3 sqrt(2) + 5, x = -3 sqrt(2) + 5

Hope this helps!

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
