Answer:
The factored form of this is (x - 7)(x -4)
Step-by-step explanation:
In order to factor quadratic equaitons with a 1 as the first coefficient, we look for two numbers that multiply to the last number (28), but add up to the middle number (-11). To do this, we often list the factors of the last number.
Factors of 28
1, 28
-1, -28
2, 14
-2, -14
4, 7
-4, -7
The numbers -4 and -7 satisfy this requirement and are therefore the numbers we want. Now we stick them into parenthesis along with x terms in the front like this:
(x - 7)(x -4)
And that is the fully factored form.

Step-by-step explanation:
The measure of angle A is 15°, and the length of side BC is 8. What are the lengths of the other two sides, rounded to the nearest tenth? AC = 29.9. AB = 30.9.
Answer: V = 1,436.03 cubic meters
Step-by-step explanation:
V = (4/3)(3.14)(r^3)
V = (4/3)(3.14)(7^3)
V = (4/3)(3.14)(343)
V = 1,436.03
