REY [17]3 years ago

Answer:

No

Step-by-step explanation:

By the converse of Pythagoras' identity.

If the longest side squared equals the sum of the squares of the other 2 sides then triangle is right.

longest side = 15

15² = 225

4² + 9² = 16 + 81 = 97 ≠ 225

Thus sides do not represent a right triangle.

-(5a+6)=2(3a+8) what is the answer
ValentinkaMS [17]

Answer:

a = -2

Step-by-step explanation:

-(5a+6)=2(3a+8)

-5a -6 = 2*3a +2*8

-5a -6a = 16+6

-11a = 22

a= -22/11

a = -2

Given the following f(x) = 3x² + 7x³ + 8x^4; g(x) = -3x + 12x² - 5x³; and h(x) = 12x +
never [62]

The value of the function (f.h)(x) is 96x⁵ + 132x⁴ + 78x³ + 18x²

<h3>How to solve function?</h3>

f(x) = 3x² + 4x³ + 8x⁴

g(x) = -3x + 12x² - 5x³

h(x) = 12x + 6

Therefore,

(f.h)(x) = f(x).h(x)

Hence,

f(x).h(x) = (3x² + 7x³ + 8x⁴)(12x + 6)

f(x).h(x) = 36x³ + 18x² + 84x⁴ + 42x³ + 96x⁵ + 48x⁴

(f.h)(x) = 96x⁵ + 84x⁴ + 48x⁴ +  36x³ + 42x³ + 18x²

(f.h)(x) =  96x⁵ + 132x⁴ + 78x³ + 18x²

How can graphs on the coordinate plane represent proportional relationships
bulgar [2K]

Answer:

Step-by-step explanation:

  • La gráfica de una función de proporcionalidad directa es una recta que pasa por el origen de coordenadas.
  • En consecuencia, para representarla sólo necesitamos un punto y el origen, los cuales uniremos mediante una línea recta. Para obtener dicho punto usaremos la ecuación.
