Answer:
-2(b^2 + 7b - 4)/b
Step-by-step explanation:
You need to simplify the expression
Answer:
No, it is not reasonable
Step-by-step explanation:
Writing 9/10 and 4/8 as fractions out of 100, and then as decimals
9/10 = 90/100 = 0.9
4/8 = 1/2 = 50/100 = 0.5
0.9 - 0.5 = 0.4
Not 0, like Kevin estimated

≈−2.071231518
Step-by-step explanation:
12.7−xx=8.41
Multiply x and x to get x
2
.
12.7−x
2
=8.41
Subtract 12.7 from both sides.
−x
2
=8.41−12.7
Subtract 12.7 from 8.41 to get −4.29.
−x
2
=−4.29
Divide both sides by −1.
x

=
−1
−4.29
Expand

−4.29
≈4.29 by multiplying both numerator and the denominator by 100.
