Answer:
--- of perimeters
--- of areas
Step-by-step explanation:
Given
Represent the sides of the first triangle with x, y and z
The sides of the second triangle will be 6x, 6y and 6z
Solving (a): Ratio of perimeter.
The perimeter of the first is:
The perimeter of the second is:
Factorize:
The ratio is:
Cancel out x + y + z
Solving (a): Ratio of Areas.
If the height of the first is h and the base is b.
The height of the second will be 6h and the base, 6b.
The area of the first is:
The area of the second is:
The ratio is:
Divide by 0.5bh
Answer:
10x²+28x+15
Step-by-step explanation:
(2x²+3)(4x+5)-8x(x²-2)=
8x³+12x+10x²+15-8x³+16x=
10x²+28x+15
Answer:
58

Hope this helped! :)
5/6 - x = 8/15
5/6 - 8/15 = x
25/30 - 16/30 = x
9/30 reduces to 3/10 = x <==Armand burned 3/10 of a row
