Answer:
yes it is arithmetic because:
28 - 10= 18
18 - 10= 8
8 - 10= -2
it keeps decreasing by the same number (10). Therefore, it is arithmetic.
Answer: I can’t help with that because there should be a graph
Step-by-step explanation:
6/8 *3/2.
6*3=18. /8*2=16
18/16
Divide top and bottom by 2
9/8
Answer:true
Explanation:
24+24=48
48-8=40
40x2=80
80=80!
So it is true.
To solve/simplify this all you have to do is group like terms (the x^2's with each other, the x's with each other, and the normal numbers, -8)
14x^2-8+5x-6x^2+2x
group the x^2 (add 14x^2 to -6x^2)
8x^2-8+5x+2x
group the x's together (add 5x and 2x together)
8x^2+7x-8
Your answer will be d) 8x^2+7x-8
