Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.

Triangle X Y Z has a base of 22 and a height of 23.1. The triangle also has a base of 31.9 and a height of 15.9.

One-half times 22 times 23.1

One-half times 15.9 times 23.1

One-half times 15.9 times 22

One-half times 22 times 31.9

One-half ties 15.9 times 31.9

One-half times 23.1 times 31.9

step-by-step explanation:

29 is x=.7

30 is y=3.375 or 3 and 3/8

x^2 + 10x + 38 + 161/x-4

to find this, you'll need to synthetically divide using synthetic division.

here's how you would set it up:

4 is what you're dividing by (set x -4 = 0)

the numbers you are 'dividing' by are 1, 6, -2, and 9 or the coefficients of the terms listed above.

bring the first term down (1), multiply that by 4 before raising it to the next term to add (6). repeat this process as so:

6 + 4 = 10; 10 x 4 = 40; 40 - 2 = 38 x 4 = 152 + 9 = 161

161 is over x-4 as there are now two constants and you cannot combine them.

also, i'm not sure if it was -9 or +9, so i assumed.

hope this !
