Answer: 0
Step-by-step explanation: when you add 25+25 it is equal to 50. when you subtract 100 from 50 it gives you -50. when you add 25+25= 50 so you add that -50 and 50 and it gives you zero (im not very good at explaining hope it helped)
Answer: x = 9
Step-by-step explanation:
x can be equal to 9.
Lets plug in 9 to the variable x, in this equation, x -3 = 6.
x - 3 = 6
9 - 3 = 6 (plugged in 9 for x)
So, x = 9.
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
