Answer:
You can use the quadratic formula
Step-by-step explanation:
X= -b +/- √b^2-4(a)(c)÷ 2(a)
Substitute and simplify to find x
Answer:
Choose the triangle that is the cutest!
Explanation
Ok so, sage green so in. I would choose it over pee yellow anytime. But that shade of purple ugh, what even is that? Only purple in is dark and magenta. Whoever created this, needs taste. Hope this is helpful :)
Hello Madoudou!
#1
So we have:
F which is the number of faces we are looking for
E which are the numbers of edges
and V the number of vertices
We can use the Euler's polyhedron formula. Which is:
V - E + F = 2
Remember we are solving for F. Thus,
F = E - V + 2
F = 9 - 6 + 2
F = 9 - 4
F = 5
The correct answer is option B
#2
It is almost the same problem. They just want us to find the vertices.
V = E - F + 2
V = 36 - 25 + 2
V = 36 - 23
V = 13
The correct answer is option C
#3
<span>The cross section formed by a plane that contains a vertical line of symmetry for a tetrahedron is a Triangle.
The correct answer is option A
#4

<span>The cross section formed by a plane that intersects three faces of a cube</span><span> is a Triangle.
The correct answer is option A
Let me know if you have any questions about the answers. As always, it is my pleasure to help students like you.

Hello from MrBillDoesMath!
Answer:
x = (1/2) (z + y)
Discussion:
Solve 2x-y =z for x.
2x -y = z =>
2x -y + y = z + y => ( add "y" to both sides)
2x = z + y
x = (1/2) (z + y) ( divide both sides by 2)
