Answer:

C) 120 degrees

Step-by-step explanation:

m<A + m<B + m<C = 180

45 + m<B + 15 = 180

m<B + 60 = 180

m<B = 120

PLEASE HELP SMART PEOPLE! This is add/subtract polynomials. h(x)+g(x) h(x)=6x^2+4x^4+7x

luda_lava [24]

Given,

$h(x) = {6x}^{2} + {4x}^{4} + 7x$

$g( x) = {6x}^{2} - 4x + {3x}^{4}$

Therefore,

$h(x) + g(x)$

$( {6x}^{2} + {4x}^{4} + 7x) + ({6x}^{2} - 4x + {3x}^{4})$

${6x}^{2} + {4x}^{4} + 7x + {6x}^{2} - 4x + {3x}^{4}$

$(4 {x}^{4} + 3 {x}^{4} ) + ( {6x}^{2} + {6x}^{2} ) + (7x - 4x)$

${7x}^{4} + {12x}^{2} + 3x$

Solving Equations In Exercise,solve the equation for e^(x)1/2 = e^3

ra1l [238]

Answer:

x = 9

Step-by-step explanation:

We are given the equation

$e^{(x)^{1/2}} = e^3$

We solve the equation in the following manner

$e^{(x)^{1/2}} = e^3\\e^{\sqrt{x}} = e^3\\\text{Comparing both the sides we get}\\\sqrt{x} = 3\\\text{Squaring both sides}\\(\sqrt{x})^2 = 3^2\\x = 9$

Solving for x, we get

$x = 9$
