Answer: The correct answer is Choice C.
For this polynomial to be a perfect square, it would need to be:
(10x + 7)^2
This will ensure that the first terms and the last terms will be 100x^ and 49. However, if you use foil to multiply the factors, you will not get 150x for the center term. Choice C also states that 150x will not be the middle term.
The answer is twelve because to Make the two fractions denominators equal you have to multiply the numerator and denominator by 4 to get the denominators equal which gets you a fraction of 12/16 and if you divide that by 1/16 because that is how long each lap is then you get 16 which is the amount of laps they swam
Answer:
Area = 28 cm² (check the attached diagram for better clarity)
Step-by-step explanation:
The question is incomplete but let's see a similar example
The front of a rectangular pyramid can refer to either one of two possibilities: it could be either the side that has the breadth and the height or the side that has the length and the height. In this case, we were given the formula for calculating the area of the front face of this rectangular prism as the product of breadth and height
Mathematically,
A = bh
From the attached diagram, we will see the properties of the rectangular prism as:
length = 5 cm, breadth = 4 cm, height = 7 cm
To calculate for the front face, we use A = bh,
⇒ A = 4 * 7 = 28 cm²
Example 2
If the breadth of the rectangular prism is 2 cm and the height is 3 cm, we have:
A = 2 * 3 = 6 cm²
Answer:
only students who have recess at 12 p.m. or later may go out
Step-by-step explanation:
Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:
y = 1.2t + 18
put y = 32
32 = 1.2t + 18
1.2t = 14
t = 14/1.2 = 11.67 hours
Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.
Hence only students who have recess at 12 p.m. or later may go out
