Answer:
5
Step-by-step explanation:
The order order operations is "PEMDAS" Which means you would solve anything with in P: Parenthesis first, anything with E: exponents second, Do M:multiplication/D:division next, and leave A:addition/S:subtraction for last.
I hope this helps, but I need to know the equation or expression to the problem to walk you through it.
Answer:
A) 0
Step-by-step explanation:
The solution is a couple (x, y) that are the coordinates of the intersection point of the lines.
If the lines are parallel there is no intersection and no solution to the system of equations
Answer:
So the roots of the polynomial are -7 , 4 , 2
Step-by-step explanation:
Given the polynomial in the question
5x³ + 5x² - 170x + 280
One of the factor of this polynomial is (x + 7)
By using remainder theorem
5x²-30x+40
-----------------------------------
x+7 | 5x³ + 5x² - 170x + 280
5x³ + 35x²
----------------------------
-30x² -170x + 280
-30x² -210x
------------------
40x + 280
40x + 280
----------------
0
So the polynomial we have is
5x²- 30x + 40
divide by 5
x² - 6x + 8
(x-4)(x-2)
So the roots of the polynomial are -7 , 4 , 2
