The first term is x^3 with coefficient 1. Let's call this p = 1
The last term is 36, so we'll call this q = 36

To find all of the possible rational roots or zeros, we divide each factor of q over each factor of p

Factors of p = 1:
-1 and 1

Factors of q = 36: 
-1, 1,
-2, 2
-3, 3
-4, 4
-6, 6
-9,9
-12, 12
-18,18
-36,36

As you can see there's a lot of possible roots. Luckily, p = 1 so that means we simply need to list the factors of q (the plus and minus versions)

The possible rational roots are listed above when I listed all the possible factors of q. Those are the possible x values that make f(x) equal to 0. You need to plug each of those values into f(x) to see which result in 0. It turns out that only x = -4 leads to f(x) = 0 being true. None of the other possible rational roots are actual rational roots.

4. What is the measure of angle ABD in the figure below?*<br> D<br> 2x<br> A<br> B<br> с
katovenus [111]

Answer:

Measure of exterior angle ABD = 136°

Step-by-step explanation:

Given:

measure of ∠A = (2x + 2)°

measure of ∠C = (x + 4)°

measure of ∠B = x°

Find:

Measure of exterior angle ABD

Computation:

Using angles sum property

∠A + ∠B + ∠C = 180°

So,

(2x + 2) + (x + 4) + x = 180

4x + 6 = 180

4x = 176

x = 44

So,

measure of ∠B = x°

measure of ∠B = 44°

Measure of exterior angle ABD = 180 - measure of ∠B

Measure of exterior angle ABD = 180 - 44

Measure of exterior angle ABD = 136°

the height of an equivalent triangle is 15cm and it's perimeter is 36cm find the area of the triangle​
OlgaM077 [116]

Answer:

The area is 72 cm².

Step-by-step explanation:

Since it is equivalent triangle

h = b

so,

b + b + b (since all sides are equal)= 36 cm

3b = 36 cm

or, b = 36/3

so, b = 12 cm

so

area of triangle = (1/2)×b×h

= (1/2)×12cm×12cm

= 6cm × 12cm

= 72 cm²
