Diego then says if we take half the first number and double the second the sum is 14. write an equation that could represent this description

x = the first number

(x/2)² = 14

Hope this helps!

Can I get brainliest? thanks.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

15.36 per mile

but forgot to round

i am pretty sure
