Ilia_Sergeevich [38]

Answer: 3x + 13

Step-by-step explanation:

$f(x)=3x^2+x\\f(a)=3a^2+a\\f(4)=3*4^2+4=52\\\\f(x)-f(4)=3x^2+x-52=(x-4)(3x+13)\\\\\dfrac{f(x)-f(4)}{x-4} =\dfrac{3x^2+x-52}{x-4} \\\\if\ x \neq 4\ then \\\\\dfrac{f(x)-f(4)}{x-4} =\dfrac{(x-4)(3x+13)}{x-4} \\\\=3x+13\\$

Find the measures of the angles in each triangle <br> 2xº<br> 3x°<br> xº

snow_lady [41]

Answer:

x = 30°

The angles:

2x° = 60°
3x° = 90°
x° = 30°

Step-by-step explanation:

Hello!

The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.

Solve the equation:

2x° + 3x° + x° = 180°
6x° = 180°
x° = 30°

We can replace 30° for all the angles.

The measures are:

2(30°) = 60°
3(30°) = 90°
1(30°) = 30°
