We know the width of the rectangle in the middle of the trapezoid is 24 (from the top of the image), so we can subtract that from the bottom width of the trapezoid to get the combined length of the bottom of both triangles.
Since this is an isosceles trapezoid, both triangle bases are the same length, so we can cut this value in half to get the length of 
and 
Finally, we can use the Pythagorean Theorem to find the length of 
:
Answer:
B
Step-by-step explanation:
F(x) is just a negative vertical shift downwards, so when you have a downwards shift the number of units down is placed right after the x outside of the parenthesis. In this case, there was a shift of -4, so it would be -x^2 - 4.
Answer:
84
Step-by-step explanation:
7 go's in to 58 8 time's bring the 8 down
you get 28 4 x 7 is 28 so it is 84
I hope this helps! Just follow the instructions.
The probability of each is the fraction of that item (or group of items) to the total. They just tried to trick you by listing Science with subcategories of biology and chemistry to see if you would add them twice and get the wrong total. Total rooms is M+S+E=5+10+10=25
S=10/25
B=8/25
M=5/25
E=10/25
C=2/25
For the "or" questions you just add them. P(MorE) = P(M) = P(E).
<span>For S and not C that's just B.
I hope my answer has come to your help. God bless and have a nice day ahead!
