An isosceles triangle has a perimeter of 36 inches. Its base is 2
astra-53 [7]

The lengths of the sides of the triangle are 8, 8, 20

Explanation:

Given that the perimeter of an isosceles triangle is 36 inches.

The base of the triangle is 2\frac{1}{2} times longer than each of its legs.

We need to determine the lengths of the sides of the triangle.

<u>Lengths of the sides:</u>

Let x denote the lengths of the sides of the triangle.

The base of the triangle is given by

2\frac{1}{2}x=\frac{5}{2}x=2.5x

Perimeter of the isosceles triangle = Sum of the three sides of the triangle.

Thus, we have,

36=x+x+2.5x

36=4.5x

8=x

Thus, the length of the sides of the isosceles triangle is 8 inches.

Base of the triangle = 2.5(8)=20 \ inches

Hence, the three sides of the isosceles triangle are 8, 8, 20

Is (x +1) a factor of <br> f(x) = x3 + 2x2 −5x − 6 ?<br><br> Yes <br> No
sertanlavr [38]

Answer:

Yes.

Step-by-step explanation:

You can find it out by factoring but ill do it easier way.

(x + 1 ) = 0 put the first and second equation to 0

x = -1

x³ + 2x² - 5x - 6 = 0  Now plug in the x in the equation

(-1)³ + 2(-1)² - 5(-1) - 6 = 0

0 = 0

so (x + 1) is a factor.
