Area=wide times long
area=40
4=wide
40=4 times long
divide both sides by 4
10=long
10 yd long
Answer:

Step-by-step explanation:
Use the distributive property.
<u>Distributive property:</u>
<h3>
⇒ A(B+C)=AB+AC</h3>
⇒ 5*5=25
⇒ 5*8=40
<u>Rewrite the problem.</u>
⇒ 5*5a+5*8
<u>Solve.</u>
<u>Multiply.</u>
⇒ 5*5a=25a
⇒ 5*8=40
<u>Rewrite the expression.</u>
<u>⇒ = 25a+40</u>
- <u>Therefore, the correct answer is 5(5a+8).</u>
I hope this helps! Let me know if you have any questions.
F(x) = -(x + 1)^2 + 4
Vertex = (-1, 4)
Domain is all real numbers.
Range is f(x) <= 4
Answer:
Step-by-step explanation:
I didn’t see any choices but an inverse function switches the x and y values.
For every (x,y) of f(x) the inverse function will have (y,x) of f^-1(x)
There are 3 face cards for each of the 4 suits, leading to a total possible gain of 120, there are 40 other cards leading to a total possible loss of 80.
120 - 80 = 40.
40 / 52 (total number of cards) = about .77
Final Answer:
The expected value of a draw is positive 0.77 points.
