AR=side2=√(hypotenuse)²-(side1)=√17²-8²=√225=15
Hello,
Cube X: volume=x
Cube Y: volume=8x
Y has a volume 2^3 times of the X cube
So,
the side of the Y cube is twice the volume of the X cube.
The side of the X cube is half of the cube Y
Side of X cube=y/2

Answer:
I can't see Mathieu's work but I will show the right steps and maybe you can find where Mathieu went wrong.
f(x)=x^2+4x+3
f(x)=(x+3)(x+1) Since 3*1=3 and 3+1=4
The x-intercepts can be found by setting y to 0 and solving for x
(in other words replace that f(x) thing with 0 and solve for x)
0=(x+3)(x+1)
Now set both factors equal to 0
x+3=0 or x+1=0
x =-3 x=-1
The x-intercepts are at (-3,0) and (-1,0)
