the answer is b i think
Step-by-step explanation:
If the triangle is a right triangle, then
(3x)² + x² = (10)² .
9x² + x² = 100
10x² = 100
x² = 10
x = √10 = approx. 3.1622...
If ' x ' is <em>anything less than √10</em> , then the short sides are too short
to make a right angle at the top, and the angle where they meet
is obtuse.
' x ' has to be greater than 2.5 ... otherwise the two short sides
can't stretch far enough to reach both ends of the long side (10) .
So, if 2.5 < x < √10 , then there is a triangle, and it's obtuse.
Answer:
1/2 or one half

Answer:
False. The products from cross multiplication are different.
Step-by-step explanation:
To know if a pair of ratios form a proportion, cross multiply. If the products are equal, they are a proportion.
Write like this to see top (numerator) and bottom (denominator) clearly.

Multiply each numerator with the other side's denominator:
4 X 6 = 24
5 X 5 = 25
Are they equal? No. 24 ≠ 25
Therefore it's not a proportion.
Answer:
You need to replace the x with the value that you want to evaluate. If the initial value is 1, you have to replace the x with1, then with 2, an finally with 3.
<em>Iteration 1.</em>
f(x=1)=3*(1)
f(x=1)=3
<em>Iteration 2.</em>
f(x=2)=3*(2)
f(x=2)=6
<em>Iteration 3.</em>
f(x=3)=3*(3)
f(x=3)=9
