Answer:
Step-by-step explanation:
The sum can be indicated by putting plus signs between the angle values:
5y +2y +2y
It can also be expressed as the simplified form of this expression:
9y
The formula for finding the lateral area for a triangular prism is

So put in the values and you get


The formula for finding the surface area of a triangular prism is
SA = bh + (s1 + s2 + s3)H
So put in all the values and you get
SA = 9(8) + (9 + 8 + 12.04)23
SA = 740
Hope this helps! :)
If the parent graph f(x) = x² is changed to f(x) = 2x², the vertex of the parabola will still remain (0, 0) because whenever the equation of a parabola is in the form y = ax², the vertex will always be (0, 0).
Now if <em>a</em> is a big number, the parabola will become narrower.
So it will stretch vertically and become narrower.
Answer:x = 1
Step-by-step explanation:
3x + x/4 = x + 3/4
Subtract x from each side
2x + x/4 = 3/4
Times each side by 4
The 4 beneath the x cancels out
3/4 x 4 = 3
2x + x = 3
3x = 3
Divide each side by 3
x = 1
