Answer:
12 m
Step-by-step explanation:
This can be solved using the Pythagorean theorem
a^2 = b^2 + c^2
20^2= 16^2 + c^2
400= 256 + c^2
400-256= c^2
144 = c^2
c = √144
c= 12
Answer:
x=4
Step-by-step explanation:
3x-5 = 7
Add 5 to each side
3x-5+5 = 7+5
3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4
Answer:
x= -5
Step-by-step explanation:
let the number be x.
2x+5= -5 ====> equation
2x= -5-5. (shifted the +5 to the other side)
2x= -10
x= -10/2 ( shifted 2 on the other side as it was multiplying with x)
x= -5
