Lostsunrise [7]4 years ago

Step-by-step explanation:

f(x) = x^4 -x^2 +9

g(x) = x^3 +3x^2 +12

We are subtracting

f(x) -g(x) =x^4 -x^2 +9 - ( x^3 +3x^2 +12)

Distribute the minus sign

x^4 -x^2 +9 -  x^3 -3x^2 -12

I like to line them up vertically

x^4      -x^2 +9

-  x^3 -3x^2 -12

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

x^4 -x^3 -4x^2 -3

2.  a1 = -7.4

To find the common difference, take term 2 and subtract term 1

-21.2 - (-7.4)

-21.2 + 7.4

-13.8

an = an-1 -13.8

if you need anymore help just ask and if you wondering i found another question which its the same one as this one so her it is

Answer:

1. x^4 -x^3 -4x^2 -3

a1 = -7.4

an = an-1 -13.8  (choice 1)

g(x) = x^3 +3x^2 +12

We are subtracting

f(x) -g(x) =x^4 -x^2 +9 - ( x^3 +3x^2 +12)

Distribute the minus sign

x^4 -x^2 +9 -  x^3 -3x^2 -12

Mariana [72]

Answer:

83

Step-by-step explanation:

Angle 7 & angle 8 are supplementary angles, meaning they add up to 180º.

Angle 8 & angle 12 are corresponding angles, so they are equal.

If we solve for the measure of angle 8, it will be the same answer as angle 12.

Therefore, angle 7 & angle 12 add up to 180º.

80 + (x+17) = 180

Solve:

(80-80) + (x+17) = 180-80

X+17 = 100

X + (17-17) = 100-17

X = 83
