The midsegment theorem says that the midsegment is half the third side and parallel as well. 20*2 is 40 so x = 35
Answer:
3.2
Step-by-step explanation:
12.8/4 which makes the answer 3.2
Next time, please share the answer choices.
Starting from scratch, it's possible to find the roots:
<span>4x^2=x^3+2x should be rearranged in descending order by powers of x:
x^3 - 4x^2 + 2x = 0. Factoring out x: </span>x(x^2 - 4x + 2) = 0
Clearly, one root is 0. We must now find the roots of (x^2 - 4x + 2):
Here we could learn a lot by graphing. The graph of y = x^2 - 4x + 2 never touches the x-axis, which tells us that (x^2 - 4x + 2) = 0 has no real roots other than x=0. You could also apply the quadratic formula here; if you do, you'll find that the discriminant is negative, meaning that you have two complex, unequal roots.
An equation will have an answer at the end like an equal sign. (Ex; 20+20=40)
An expression will NOT have an answer. (Ex; 20+20)
