Question

I need help pls these are confusing​

Answer 1

216

249

Explanation:

First Q:

h = u - 4

t = 1

(u-4)(1)(u) = 12

u² - 4u = 12

u² - 4u - 12 = 0

(u-6)(u+2) = 0

u = 6, -2 disregard the negative root

h = 6-4 = 2

Therefore, the number is 216

Second Q:

Just start guessing; start with the lowest prime number, 2, and see if it works.

h = 2

t = 2h = 2(2) = 4

u is odd, so the lowest digit that is a square and less than 4 is 9

Therefore, the number is 249

Answer 2

First one is: 216

Second one is: 249

Explanation:

Explanation for the first one:

•Its even

•The tens digit is 1

•If you multiple each one one will get 12

•h is less than u

Explanation for the second one:

•Its odd

•u is more than t

•h is prime

•t=2h --> 4=2x2

•4 is a square number (2x2) and 9 is also a square number (3x3)
