Answer:

Step-by-step explanation:

The two inside angles will sum to 180°.

The top to angles are equal.

Think about this as what if both of the parallel lines were intersected by a perpendicuar line. Every angle would be a right triangle 90°. The inside angles will sum to 180° and the opposite angles are again equal.

(2x + 18) + (8x + 12) = 180

10x + 30 = 180

10x = 150

x = 15

-------------------------

(3y - 18) = (8x + 12) x = 15

(3y - 18) = (8(15) + 12)

(3y - 18) = (120 + 12)

(3y - 18) = 132

3y = 132 + 18

3y = 150

y = 50

What is the complete factorization of the polynomial function over the set of complex numbers? f(x)=x^3+3x^2+16x+48

Tamiku [17]

Answer: $(x+3)(x+4i)(x-4i)$ is the required factorization of f(x).

Step-by-step explanation:

To factor the expression we must first group the terms and then take out common from these groups

$f(x)=x^3+3x^2+16x+48=(x^3+3x^2)+(16x+48)$

Taking $x^2$ common from first group and the 16 from second group we get:

$f(x) = x^2(x+3)+16(x+3) = (x+3)(x^2+16)$

Now, to factor in complex from we have to break term $x^2+16$

$f(x)= (x+3){x^2-(-4i)^2}$

As, $i^2 = -1 , therefore (-4i)^2 = 16i^2 =-16$

Also using identity $a^2-b^2 =(a+b)(a-b)$

On solving

$f(x) = (x+3)(x+4i)(x-4i)$

$(x+3)(x+4i)(x-4i)$ is the required factorization of f(x).

Answer:

The perimeter is 30 and the angle is 53.

Step-by-step explanation:

The perimeter is found by adding the length of all four sides. Two sides are 10 units and two sides are 5 units. 10+10+5+5 = 30.

The angle is found by subtracting angle ABC's value from 180.

180 - 127 = 53.
