Answer:
5/8 + 7/12 =29/24
Step-by-step explanation:
When we multiply the polynomials we will get:
(5x^2+2x)(3x^2-7x+4)
=5x^2(3x^2-7x+4)+2x(3x^2-7x+4)
=15x^4-35x^3+20x^2+6x^3-14x^2+8x
=15x^4+(6x^3-35x^3)+(20x^2-14x^2)+8x
=15x^4-29x^3+6x^2+8x
The correct answer is C
Answer: -2511 (if the periods mean multiplication)
Step-by-step explanation:
I’m not sure whether you’re trying to have the periods be multiplication, but if that’s what they are, this is the answer
5x10-2x8x16x10-1
50-16x160-1
50-2560-1
-2511
Again, I’m not sure if that’s what you mean but I can’t really see what else they would mean since you can’t have a 3 part decimal
Answer:
C
Step-by-step explanation:
A function is constant when the y value does not change when the x value does
The function is constant during section C
Answer:
2.
4x^2 + 4 - 5x + x - 2x^2 + 8
= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)
= 2x^2 - 4x + 12
=> D is correct
3.
2x^2 + 6x - 7x + 8 - 3x^2 + 1
= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)
= -x^2 - x + 9
=> C is correct
4.
B is correct (4 and 3)
Hope this helps!
