100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.
Assoli18 [71]

The factors of the equation x^2-3x-18 are (x-6)(x+3)

Step-by-step explanation:

We need to factor the quadratic trinomial. x^2-3x-18

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)

So, the factors of the equation x^2-3x-18 are (x-6)(x+3)

The difference of two complementary angles is 48. Find the measures of the two angles.
Furkat [3]

The larger angle is 55 deg at the larger angle.

We have to know which angles are called Complementary Angles...

if we add two angles and the total will be equal to 90 deg

let's say one angle is x and  another angle is  y

as they are complementary angles from the definition we can write the equation x + y =  90

one angle is 20 deg more  than another one  so from the above condition  we write x = 20 + y

Substitute the value of x  in the first eaquation we get, 20 + y + y =  90

Then,  20 + 2y =  90

subtracting 20 from both sides,

 2y  =  90-20 = 70  

 dividing both sides by 2,

2y/ 2 = 70 / 2

 y  =  35

 So we got one angle is 35 deg

another angle is  35 + 20 = 55 deg.

Our answer is 55 deg the larger angle.

If f(x)= |x^3-3| then f(-1) is equivalent to
emmasim [6.3K]

Hello from MrBillDoesMath!

Answer:

4

Discussion:

f(x) =  abs (x^3 - 3)        =>

f(-1) = abs ( (-1)^3 -3 )    =>        (-1)^3 =  -1

f(-1) = abs( -1 -3 )           =>       -1 =3 = -4

f(-1) = abs(-4)               =>

f(-1) = 4

Thank you,

MrB
