Answer:
Step-by-step explanation:
The answer is 4.
Once you add 4, you get:
x^2 -2x + 4 = 7.
The left side is factorable:
(x-2)^2 = 7.
There is your perfect square.
A) f + s + t = 148
B) f + 10 = s
C) t = 4 * f
Substituting C) into A)
A) f + s + 4f = 148
Substituting B) into A)
A) f + f + 10 + 4f = 148
A) 6f = 138
f = 23
B) f + 10 = s
s = 33
t = 4 * 23
t = 92
23 + 33 + 92 = 148
Hope you understand. tell me if u need help
4(m+3) =10m-6
4m +12= 10m-6 Expanded the brackets
12= 6m -6 took away 4m from both sides
18=6m added 6 to both sides
m=3 divided both sides by 6
