hello here is an solution
745 centimeters is your answer. do you want me to extend your answer? be specific on the question :))))
Assume that 40 percent of X is 55
<span>This means X (40 / 100) = 55 </span>
<span>0.4 X = 55 </span>
<span>X = 55 / 0.4 </span>
<span>X = 137.5 </span>
<span>55 is 40 percent of 137.5</span>
Answer:
2x³ + 4x² - 2x - 4
Step-by-step explanation:
Expand the first pair of factors then multiply by (2x + 2)
= (x² + x - 2)(2x + 2) → distribute terms
= x²(2x + 2) + x(2x + 2) - 2(2x + 2)
= 2x³ + 2x² + 2x² + 2x - 4x - 4 ( collect like terms )
= 2x³ + 4x² - 2x - 4 ← in standard form
