Answer:
To find a b and c in a quadratic equation, the x^2 number is a, so 7x^2 is your a value, your b value is just the x, so your b value is -9, and your c value is the regular number, which is 18. a=7x^2 b=-9x c = 18. So your answer is answer B.
Step-by-step explanation:
<u><em>Matteo is 4 inches taller than Nico. </em></u>
<u><em>Sarah is wrong because she didn't consider the conversion rate from ft to inches. </em></u>
Height of Matteo = 4 feet 3 inches
Height of Nico = 3 feet 11 inches.
- Now to find the difference in height, we need to first convert both of their heights to inches.
From conversion tables, we know that;
12 inches = 1 ft.
- Thus, their height in inches is;
Height of Matteo = (4 × 12) + 3 = 51 inches
Height of Nico = (3 × 12) + 11 = 47 inches
Thus, difference in height = 51 - 47 = 4 inches.
Thus, Matteo is 4 inches taller than Nico.
- Looking at the method of Sarah, she didn't consider that the unit she was working with. If it was just units and tens subtraction, that method would have worked but she ought to have added 12 to 3 since it is from ft to inches instead of 10 to 3 as in the case of regular numbers without units.

First, you would get the decimal form of 67% by moving the decimal (At the end of most whole numbers.) over two, giving you .67.
Next, multiply 296 by this new decimal- .67*296=198.32.
There you go! : )
The ratio of suitcases to screened suitcases is 36:8. The second ratio is 180:?.
--
180 is 5 times 36 which can be proven by dividing 180 by 36.
180 ÷ 36 = 5
Multiply 5 by 8 to find the amount of suitcases that would be screened if there were 180 total suitcases.
5 × 8 = 40
The first ratio is 36:8, and with a scale factor of 5 we get the second equivalent ratio 180:40.
<h2>Answer:</h2>
<u>Forty suitcases</u><u> will be screened.</u>
