Should there be a graph or something? Or an equation?
Answer:
<h2>V = x³ + 54x² + 936x + 5,184</h2>
Step-by-step explanation:
<h3 /><h3>If we add a value of 'x' to each side of the box, the new dimensions can be represented as</h3><h3>x + 24</h3><h3>x + 12 and </h3><h3>x + 18</h3><h3 /><h3>To find the volume of the new box, multiply all of the dimensions together</h3><h3 /><h3>V = (x + 24)(x + 12)(x + 18) </h3><h3> Foil the first and second binomial....</h3><h3 /><h3>V = (x² + 36x + 288)(x + 18)</h3><h3> Now multiply the two polynomials together...</h3><h3 /><h3>V = x²(x) + 36x(x) + 288x + x²(18) + 36x(18) + 288(18)</h3><h3 /><h3>V = x³ + 36x² + 288x + 18x² + 648x + 5,184</h3><h3 /><h3>which simplifies to</h3><h3 /><h3>V = x³ + 54x² + 936x + 5,184 where x represents the increase in inches</h3>
Answer:
no
Step-by-step explanation:
to be proportional, every step of 1 in the upper row, must equal an equal step in the lower row.
from 1 to 2: +15
from 2 to 3: +18
not the same so not proportional
Y = 12
First, I remembered that complementary angles are angles that add together to get 90 and supplementary angles are angles that add together to get 180. Next I subtracted 102 from 180 and got 78, which means that x = 78. Then I subtracted 78 (x) from 90 and got 12 (y).
