Answer:

The factored form is (3+ x^2)(5 + 2x)

Step-by-step explanation:

I.I rewrited it as 15 + 5x^2 + 6x + 2x^2

= 5(3 + x^2) + 2x(3 + x^2)

= $(3 + x^{2})(5 + 2x^{})$

II. Prove by

= 3(5) + 3(2x) + x^2(5) + x^2(2x)

= 15 + 6x + 5x^2 + 2x^3

That makes = 2x^3 + 5x^2 + 6x + 15

Find the measure of each acute angle in the figure.

Artist 52 [7]

Answer:

Angle 1 = 46°

Angle 2 = 44°

Step-by-step explanation:

Given:

Angle 1 = (4x - 2)°

Angle 2 = (3x + 8)°

Angle 3 = 90°

Find:

All acute angle

Computation:

Using angle sum property

Angle 1 + Angle 1 + Angle 1 = 180°

(4x - 2)° + (3x + 8)° + 90° = 180°

7x + 6 = 90

7x = 84

x = 12°

So,

Angle 1 = (4x - 2)° = 4(12) - 2 = 46°

Angle 2 = (3x + 8)° = 3(12) + 8 = 44°

Which represents the reflection of f(x)=sqrt x over the y axis

zloy xaker [14]

reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be $g(x)= f(-x)$

So, finding reflection of $f(x)=\sqrt{x}$ over the y axis we get:

$g(x)=\sqrt{-x}$

So, reflection of $f(x)=\sqrt{x}$ over the y axis we get $g(x)=\sqrt{-x}$
