Answer:
I think 9 inches.
Step-by-step explanation:
Answer:
9(p + 4)
Step-by-step explanation:
One of the unknown variable is p.
First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).
Translating the word problem into an algebraic expression, we have;
9 * (p + 4) = 9(p + 4)
Simplifying further, we have;
9p + 36
The sum of the polynomials (8x²-9y²-4x)+(x²-3y²<span>-7x) is:
1. You must add the terms whose variables and exponents are the same.
2. Let's rewrite the polynomials:
</span>
(8x²-9y²-4x)+(x²-3y²-7x)
8x²-9y²-4x+x²-3y²-7x
(8+1)x²+(-4-7)x+(-9-3)y²
3. Therefore, the result is:
9x²-11x-12y²
3. <span>What is the sum of the polynomials?
The answer is: </span>9x²-11x-12y²
