Question

5k²-90=410 solve for each variable​

Answer 1

Answer:

10

Step-by-step explanation:

5K^2 - 90 = 410

5K^2 = 410 + 90

5K^2 = 500

K^2 = 500/5

K^2 = 100

K = √100

K = 10

Answer 2

Answer:

K = 10

Step-by-step explanation:

5k^2 = 410 + 90 = 500

K^2= 500÷5 = 100

K = square root of 100 = 10×10 = 10

Thus k = 10
