D. -4/3
Let's solve your equation step-by-step.
9x2+24x+20=4
Step 1: Subtract 4 from both sides.
9x2+24x+20−4=4−4
9x2+24x+16=0
Step 2: Factor left side of equation.
(3x+4)(3x+4)=0
Step 3: Set factors equal to 0.
3x+4=0 or 3x+4=0
x=
−4
/3

Answer:
Expression: 
Value of the expression when 
: 
Step-by-step explanation:
Let's first focus on the expression: '6 more than twice a number'. Twice a number is the same as saying two times a number. Let's have that number be represented by 
. Twice a number would mean 
, and 6 more than that would just be .
We'll then plug in 5 for to get the value of the expressinn:
e^x=170
because you subtract like terms (or add, it depends) then simplify (im bad at explaining)
