The answer is the second option, which is 28x + 8y + 2.
Answer:
True
Step-by-step explanation:
If there are an equal amount of red and blue marbles, then the statement would be true, since there's just as many red marbles in the jar as there are blue marbles.
Answer + Explanation + Theory
When a number is divided by a number it results in a quotient and a remainder
E.g. 9 / 4 = 2 remainder 1
9 is the dividend
4 is the divisor
2 is the quotient
1 is the remainder
Same way when a polynomial is divided by a linear expression
E.g.
Ax^2 + bx + c / (x-b) = (x+a) + r
Which can be rearranged to
ax^2 + bx + c = (x+a)(x-b) + r
When x = - a or b, only the remainder is left since either (x+a)(x-b) is 0.
If x = - a or b is substituted into the polynomial and the value is 0 then there is no remainder,
This would suggest (x+a) or (x-b) are factors of the polynomial.
Now apply this logic to these questions
1. Let’s assume (x-4) is a factor, this would mean that when x=4 is substituted into the polynomial the answer would be 0.
This is the case, therefore the remainder is 0.
2. Having seen the logic above (applied using the remainder and factor theorem) the linear expression is a factor of the polynomial.
Answer: I think the answer is 10???
Step-by-step explanation:
you can use the formula pq/2 where p is the horizontal length and q is the vertical length. Then you do 2(10)/2. This is 20/2 which becomes 10 sq units. Correct me if I am wrong though
