Hey there,
The question given is as follows:
- (3x² - 4x + 8) + (-x² - 2x - 8)
When we add polynomials we add like terms (e.x. we add 3x² with -x²) and combine the two to make one polynomial. When we add the two polynomials given above:
So our answer to the problem would be 2x² - 6x.
Hope I helped,

Answer:
64 degrees
Step-by-step explanation:
The interior angles of a triangle must add up to 180 degrees. So, we can add up the other two, known angles to get 116. Subtract 116 from 180 (180-116) to get 64.
Answer:
53.52°
Step-by-step explanation:
cos x° = 22/37 = 0.59456
x = 53.52°
6 semicircles = 3 circles
The formula of the area of a equilateral triangle:
We have a = |AE| = 3cm. Substitute:
The formula of the area of a circle:
We have 2r = |AE| =3cm → r = 1.5cm. Substitute:
The area of the figure:
Answer:
c = 10
Step-by-step explanation:
The pythagoras theorem :
a² + b² = c²
a = 6 and b = 8
6² + 8² = c²
36+64 = c²
100 = c²
c = √100
c= 10
Hope this helped and brainliest please
