Answer:
38x² - 17x - 3
Step-by-step explanation:
The area of the shaded region is calculated as
area of outer rectangle - area of white rectangle, that is
(8x + 1)(5x - 3) - 2x(x - 1) ← expand (8x - 1)(5x - 3) using FOIL
= 40x² - 24x + 5x - 3 - 2x² + 2x ← collect like terms
= 40x² - 17x - 3
Answer:
To do this, subtract 6 from both sides. − 3_x_ + 6 − 6 > 12 − 6. −3_x_ > 6. Now divide both sides of the inequality by −3. Since you're dividing by a negative number, you need to flip the inequality sign.

Answer:
the one that looks closest to this
Step-by-step explanation:
14 girls are in the class
the ratio 7:5 is divided by two so it can also be seen as 14:10. Add four boys and the ratio becomes 14:14 which is also 1:1
0.31 = 31%
% is out of 100 so 31% is 31 out of 100 which is 31/100 :)
