Answer:
30
Step-by-step explanation:
75% can also be written as 3/4. 3/4 can also be written as 30/40, or 30 out of 40, which in this case, means 30 out of 40 kids.
A2 - (B + C) = (3x - 4)2 - ((x + 7)+ (x2 + 2))
<span>A2 - (B + C) = 9x2 - 24x + 16 - (x2 + x + 9)
</span><span>A2 - (B + C) = 9x2 - 24x + 16 - x2 - x - 9
</span><span>A2 - (B + C) = 8x2 - 25x + 7
</span>
So, the answer is
<span>A:
8x2 – 25x + 7</span>
Answer:
4x^2
Step-by-step explanation:
2x^3*8x^5
