Answer:
A = x⁵ + 13x³ - 9x² + 40x - 72
Step-by-step explanation:
The formula for the area of a rectangle is length X width, or A = lw.
Substitute the equations for the sides into the formula:
A = lw
A = (x² + 8)(x³ + 5x - 9) <= use the distributive property
A = x⁵ + 5x³ -9x² + 8x³ + 40x - 72 <= collect like terms
A = x⁵ + 13x³ - 9x² + 40x - 72
7.5. 10.5*5 and divide that by 7
Answer:
7x4/8=3.5
9 × 7/10=6.3
(i dont know this one or the next, hope it helps! ❤
Step-by-step explanation:
17.45 = 17 <u>45</u>
100 and you can divide the numerator and denominator by 5
so the final answer is 17 <u> 9
</u> 20<u>
