Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
Answer:
42.5
Step-by-step explanation:
divide it by 8.
Answer:
v=7
Step-by-step explanation:
i just used a math website for my answers and told it to simplify. try using that website. i always get an 90-100's on my tests from using that
In geometry, the angle bisector<span> theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite </span>angle<span>. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
so the answer is B</span>
But sometimes things can grow (or the opposite: decay) exponentially, at least for a while.
So we have a generally useful formula:
y(t) = a × ekt
Where y(t) = value at time "t"
a = value at the start
k = rate of growth (when >0) or decay (when <0)
t = time
