Answer:
<em>f( g ( - 2 ) ) = - 14 </em>
Step-by-step explanation:
f(x) = - 2x + 4
g(x) = 3x² - x - 5
f( g ( - 2 ) ) = ?
g( - 2 ) = 3( - 2 )² - ( - 2 ) - 5 = 12 + 2 - 5 = 9
f(9) = - 2 × 9 + 4 = - 14
<em>f( g ( - 2 ) ) = - 14</em>
Check the picture below.
running a perpendicular line like so from the right-angle, makes three similar triangles, the large, containing the smaller ones, and a medium and a small one. Now, using proportions, you can just use there, the medium and smalle to get "x".
7*4=28
7-4=3
so the width is 4 feet and the length is 7 feet
8 tens and 3 ones.
hope that helped
Answer:
30 ft of dirt.
Step-by-step explanation:
We want to know the volume, or the capacity, of the hole.
The formula for volume is to multiply the length, width, and height.
l x w x h
2 x 5 x 3 = 30
So there is 30 ft of dirt in the hole.
