Answer:
<em>The binomial is a factor</em>
Step-by-step explanation:
In order to show that x+3 is a factor of the polynomial, then;
f(a) = 0
Get a by equating x+3 to zero
x+3 = 0
x = -3
Get f(-3)
f(-3) = (-3)^4 + 8(-3)^3 + 11(-3)^2 -11(-3) + 3
f(-3) = 81 - 216 + 99 + 33 + 3
f(-3) = 216-216
f(-3) = 0
<em>Since the remainder of the polynomial when divided by x+3 is zero, this shows that x+3 is a factor of the given polynomial</em>

Subtract 5y - 8 from 2y + 8
To subtract two numbers, we can do it like this:
10 - 4 = 10 + (-4)
That is, add the first number with the second number with its sign changed. For simple numbers, it does not make much difference, but for algebraic expressions, it can help a lot.
To subtract both binomials, we write the first plus the second with changed signs:
2y + 8
-5y + 8
---------------
-3y + 16
The result of the subtraction is -3y+16
240is the answer for the question 16
Step-by-step explanation:
m <em>L</em><em> </em>1 = 180°-75° = 105° ( angles in one side)
m <em>L</em><em> </em>2 = 75° (corresponding angles)
