An isosceles triangle has a base 9.2 units long. If the congruent side lengths have measures to the first decimal place, what is
Nadusha1986 [10]

Question:

An isosceles triangle has a base of 9.6 units long. If the congruent side lengths have measures to the first decimal place, what is the possible length of the sides? 9.7, 4.9, or 4.7

Answer:

4.9 is the shortest possible length of the sides.

Step-by-step explanation:

Given:

The base of the triangle base  =   9.2 units

To Find:

The shortest possible length of the sides = ?

Solution:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

So According to the theorem

x+x > 9.6

2x > 9.6

x > \frac{9.6}{2}

x > 4.8

In the given option 4.9 is the shortest length greater than 4.8 that can be possible.

Y^2 + 6y + 9 = 49 factor
andreev551 [17]
(y+10)(y-4)

Explanation:
In order to solve you must set the equation to 0. Meaning you subtract 49 from 9 to get the original equation to now be y^2+6y-40.
You then set that equation (y^2+6y-40) to zero in order to factor it out.
To do this, you have to find two numbers that multiply to make -40 but add to make 6, which is where you get 10 and -4.
Hope this helped! :)
