5x+2y=29
x+4y=13
eliminate y's

multiply top equation by -2 and add to first

-10x-4y=-58
<u>x+4y=13 +</u>
-9x+0y=-45

-9x=-45
divide  both sides by -9
x=5
sub baack

x+4y=13
5+4y=13
minus 5 both sides
4y=8
divide both sidse by 4
y=2

x=5
y=2
(x,y)
(5,2)

Name the prism in each case given that all lateral faces are rectangles and the bases are: Equilateral triangles
Cloud [144]
This is a triangular prism.

The lateral faces are triangles; this means that the two bases are parallel to one another.  This makes it a prism instead of a pyramid.

The bases being triangles makes it a triangular prism.

Which quadratic equation equation is equivalent to (x^2-1)^2 -11(^2-1) +24=0
cluponka [151]
(x^2-1)^2-11(x^2-1)+24=0

Use substitution: x^2-1=t

t^2-11t+24=0\\\\t^2-8t-3t+24=0\\\\t(t-8)-3(t-8)=0\\\\(t-8)(t-3)=0\iff t-8=0\ \vee\ t-3=0\\\\t=8\ \vee\ t=3

<span>we're going back to substitution:

x^2-1=8\ \vee\ x^2-1=3\ \ \ \ |add\ 1\ to\ both\ sides\ of\ the\ equations\\\\x^2=9\ \vee\ x^2=4

therefore

x=\pm\sqrt9\ \vee\ x=\pm\sqrt4\\\\\boxed{x=-3\ \vee\ x=3\ \vee\ x=-2\ \vee\ x=2}
