Answer:
6. 3x^3-7x^2+4x-1
7. -6x^4-2x^2+6x+10
8. 42x^4
Step-by-step explanation:
GLH + HLI = 90
9m + (25m + 22) = 90
34m = 90 -22
m = 68/34
m = 2
In short, Your Answer would be 2
Hope this helps!
I believe it is the final choice because it correctly compares 2 sets of corresponding sides.
Hey there!

Formula for the area of a triangle is (1/2)bh.
Base of this triangle is 5, height is 4.
Image attached.
Plug values into the formula:
A = (1/2)(5)(4)
Simplify.
A = (1/2)(20)
A = 10
Area of the triangle is 10 units².
Hope this helps!
