X^2+4x+4=8
-8 -8
subtract 8 from both sides
x^2+4x-4=0
now factor using quadratic formula
ax^2+bx+c=0
x= -b +-[ (sqrt (b^2-4ac))/2a ]
x=-2(1+sqrt(2))
x= 2(sqrt(2) -1)
hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help
Answer:
It would take him 4 hrs
Step-by-step explanation:
and 40 or 4 mins
The corresponding sides are
LN to XZ
LM to XY
NM to ZY
We have NM=3 and ZY=9
The scale factor is 9÷3=3
XZ = 2×3 = 6 units
LM = 12÷3 = 4 units
The correct answer is <span>LM is 4 units and XZ is 6 units</span>
Answer:160
Step-by-step explanation:
With the way the equation is written, we can assume that the “x2” is x multiplied by 2.
The x2 and 9x are like terms, and can be simplified to 11x.
Our new equation is
f(x) = 11x + 18
With no exponential functions in the equation, the difference of each value’s output would be 11.
