Answer:
x = 1/2
Step-by-step explanation:
(x + 2)2 + (9 - 3)2 = 4
2x + 4 + 18 - 6 = 4
2x + 16 = 4
2x = 4/16
2x = 1/4
x = 1/4/2
x = 2/4
x = 1/2
a = 56
given 28 = 
a
multiply both sides by 2 to eliminate the fraction
56 = a
As a check
× 56 = 28 ← True

Answer:
5/4
Step-by-step explanation:
, open the bracket
3=28-14u-6u
Collect like terms
3-28=-14u-6u
-25 =-20u
Divide both side by -20
u=-25/-20. Minus sign will cancel each other and reduce to the lowest term
u=5/4
