Step-by-step explanation:
the surface area of that object consists of
2 triangles (one left, one right)
1 rectangle at the top
1 rectangle at the bottom
1 rectangle in the back
so, we need to calculate the area of each of these 5 areas and sum them up. that's it.
the area of such a triangle is
6×8/2 = 24 m²
we have 2 such triangles, so in total they are 48 m².
the rectangle at the top
10×12 = 120 m²
the rectangle at the bottom
12×8 = 96 m²
the rectangle in the back
12×6 = 72 m²
so the total surface area is
48 + 120 + 96 + 72 = 336 m²
Answer:
~Re-write the equation~
SOLVE:
5x(3)+4x (2-9)+(2x+1)+(2x2+x-3)
5(1)(3)=15
4(2-9)=8+36=44
2x+1=3
2x2+x-3:4(1)-3=1
15+44+3+1
ANSWER=63x

I wasn't quite sure because of the way you wrote it but here's an answer!
Answer:
(1, -10)
Step-by-step explanation:
Only the y can be on the left hand side. The square has been completed so all you need do is transfer the 10 to the right and read the x,y values for the vertex.
I have provided a graph to show you that the vertex and my answer are the same (hopefully).
y + 10 = 4(x - 1)^2 Subtract 10 from both sides.
y + 10-10=4(x -1)^2 -10 Combine
y = 4(x - 1)^2 - 10
Now we need to make the square term = 0
x - 1 = 0 Add 1 to both sides
x - 1 + 1 = 0 +1 Combine
x = 1 When x = 1 the square term will equal 0.
The vertex should be (1, - 10)
Answer: hi, i can’t see the photo
Step-by-step explanation:
There are 10 students so that is 2/10 which reduces down to 1/5
