Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112
Answer:
Undefined
General Formulas and Concepts:
- Slope of horizontal and vertical lines
Step-by-Step Explanation:
A vertical line always has an undefined slope. There is no such value m of slope that can make a vertical line, and thus we reach the conclusion of undef.
Answer:
a= 37
Step-by-step explanation:
All the angles of a triangle add up to 180° so if you add 110 with 35 it equals 145, then subtract 145 by 180 and you get 37
15 and 6.
15+ 6 = 21
15^2 + 6^2 = 261
360 .each centimeter is 10 millimeters
