Answer:
38260
Step-by-step explanation:
ur welcome
first we need to get rid of the ( ) so that we can see what the question really says
(3x³-5x² - 7+ 4x4) + (9x4 - 10x² - 5x³ + 3)
= 3x³-5x²-7+4x⁴+9x⁴-10x²-5x³+3
now all we need to do is add up the numbers with the same x's
<em>3x³</em>-5x²-7<u>+4x⁴+9x⁴</u>-10x²<em>-5x³</em>+3
= 13x⁴-2x³-15x²-4
They could look at the length of the book and the size of the font to estimate the length of a book.
X^2 + y^2 - x^2 +y^2
That would be (1x+1y)-(1x+1y)
