Please help ASAP! Will give BRAINLIEST! Please read the question THEN answer correctly! No guessing.
ElenaW [278]

Answer:

x =  -2 ±sqrt(7)

Step-by-step explanation:

3x^2 +12 x = 9

Divide each side by 3

3x^2 /3 +12x/3 = 9/3

x^2 +4x = 3

Take the coefficient of x

4

Divide by 2

4/2 =2

Square it

2^2 =4

Add it to each side

x^2 +4x+4 = 3+4

x^2 +4x+4 = 7

(x+2)^2 = 7

Take the square root of each side

x+2 = ±sqrt(7)

Subtract 2 from each side

x+2-2 = -2 ±sqrt(7)

x =  -2 ±sqrt(7)

What is the value of 1/3 x^2 + 5.2y when x = 3 and y = 2?<br><br> PLZ HELP!!!
olasank [31]
The first step in solving this is to substitute x with 3 and y with 2, so that
\frac{1}{3} x^{2} +5.2y
becomes
\frac{1}{3}  (3)^{2} +5.2(2)
Then simply solve using the order of operations.
First exponents (there are no parentheses)
\frac{1}{3} 9 +5.2(2)
Then multiply and divide
3+10.4
And finally add and subtract
13.4
Therefore the value <span>of 1/3 x^2 + 5.2y when x=3 and y=2 is 13.4</span>
