Answer 5

so you know the formula to find the area of the triangle substitute the expressions and simplify.
use what you know to find the unknown

Answer 6

find the Area
1/2 * base * height
1/2 * (x^2+2x+4) * (2x^2+2x+6)

Answer 7

I tried but it didn't work :(

Answer 8

I got 2x^3+6x^2+22x+12

Answer 9

(x +2)(x^2 + x + 3)

Answer 10

x^3 + x^2 + 3 x + 2 x^2 + 2 x + 6

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

Answer 11

check your term in x and did you divide by 2 ?

Answer 12

yes

Answer 13

I tried two times but I still couldn't get it :(

Answer 14

is my answer correct? do you want to post what you did?
the difference between mine and yours is the term in x and the factor

Answer 15

sorry, your answer wasn't one of my choices

Answer 16

i have an error (x +2)(x^2 + x + 3) should be (x +2)^2

Answer 17

Area =(x^3 + 3 x^2 + 5 x + 6 )(x + 2)
= x^4 + 5 x ^3 + 11 x ^2 + 16 x + 12

Answer 18

sorry, my choices are

A. 3x^4+9x^2+10x+12
B. x^4 +3x^3+9x^2+10x+12
C. 3x^4+3x^3+9x^2+10x+12
D. x^4+9x^2+10x+12

Answer 19

x^4 + 3 x^3 + 9 x^2 + 10 x + 12

Answer 20

the correct answer is B

Answer 21

re do
the process is correct
1/2 * 2(x^2 + x + 3)(x^2 + 2 x + 4)

Answer 22

thank you :)

Answer 23

sorry about my previous calculation errors
you are welcome
