I’m pretty sure surface area is all the sides multiples then added
I’m going to assume the length is 10, width is 4, and height is 3
You would find the base of the rectangle which is the same as the top and that would be 80 (because 10 multiples by 4 for the base and top)
Then the ends which is 3x4= 12 and you have to sides so the total is 24
And lastly the sides which is 10x3= 30 and you have 2 sides so it’s really 60
In total you have 60+24+80= 164cm

Answer:

y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}

Step-by-step explanation:

Given equation:

y = 3x^2 - 9x + 17

Factor out 3 from the first 2 terms:

y = 3(x^2 - 3x) + 17

Divide the coefficient of x by 2 and square it:  (-3 ÷ 2)² = 9/4

Add this inside the parentheses and subtract the distributed value of it outside the parentheses:

y = 3\left(x^2 - 3x+\dfrac{9}{4}\right) + 17-\dfrac{27}{4}

Factor the parentheses and combine the constants:

y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}
