9y(8y² - 2y + 4)
9y(8y²) - 9y(2y) + 9y(4)
72y³ - 18y² + 36y
Answer:
<h3>
9, 10 and 11</h3>
Step-by-step explanation:
x - the smallest of three consecutive integers (the first)
x+1 - the next of three consecutive integers (the second)
x+2 - the last of three consecutive integers (the third)
3(x+2) - three times the third integer
<u>3(x+2)+x </u> - three times the third increased by the first
5(x+1) - five times the second tnteger
<u>5(x+1)-8 </u> - 8 less than five times the second
3(x + 2) + x = 5(x + 1) - 8
3x + 6 + x = 5x + 5 - 8
4x + 6 = 5x - 3
-4x -4x
6 = x - 3
x = 9
x+1 = 10
x+2 = 11
Check: 3×11+9 = 33+9 = <u>42</u>, 5×10-8=50-8 = <u>42</u>
Answer:
it would be about 63.44..
Step-by-step explanation:
you can do 230/87=24/x where x is the new height, when you cross multiply and divide, x should be about 63
Answer:
f(x) = 2/x and g(x) = 2/x
f(g(x)) = f(2/x) = 2/(2/x) = x
g(f(x)) = g(2/x) = 2/(2/x) = x
The altitude of a triangle (in the sense it used here) is a line which passes through a vertex<span> of the triangle and is perpendicular to the opposite side. There are therefore three altitudes possible, one from each vertex.
