Answer:
21.6 m long
Step-by-step explanation:
To do this, we find the scale factor of the fencepost and the shadow.
3/1.8 = 1.66666667
So, we know that when we take the original length and multiply it, we get the new one, so:
1.666666667 * x = 36
x being the original length. Now, we divide both sides by 1.66666667 to get x alone and find the original length.
x = 21.6
To double check, we can take the scale factor and multiply it by the original to get the shadow.
21.6 * 1.666666667 = 36
It is correct
Answer:
34 because the shape is split.
Step-by-step explanation:
(t-4)(t+8)
Smallest:-8✨
Largest:4✨
Answers are when function is zero
And the vertex is solving like this:
t2+4t-32=0
Vertex: -b/2a
Vertex: -4/2= -2✨
now our t is -2 so—> solve it when t is -2 and the answer is (-2,-36)✨
Step-by-step explanation:
Perimeter of a rectangle= 2(l+b)
= 2( 4m-1+3m+2)
=2(7m+1)
= 14m+2
