Answer:
5 (x+2) +2x is equal to 7x + 10
Step-by-step explanation:
To find the value of this equation you would have to apply the distributive property by changing 5 (x+2) to 5x +10. (When applying the distributive property you will always multiply the numbers in the parentheses by the number on the left of it). Then you would combine like terms by adding 2x and 5x together. You will then have 7x + 10.
9.4 × 
1) Move the decimal point 2 times to left in the number so that number, 940 so it's between 1-10: 9.4 or 9.40
2) After we moved our decimal point to the left, the decimal count would be 12 and that we moved 2 places to the left
3) We know that the notation is a x 
a=9.4 and 6=2
9.4 × =a x

Answer:
<em>3 seconds</em>
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
<em>hence it will take 3 seconds until Devon hit the water</em>
Answer:
This may not be entirely satisfied proof but you should get the idea.
Proof: Start with 1 = -1.
Then we know that if a= b then a + c = b + c and also a / c = b / c.
So we can add 1 to both sides.
We have 1 + 1 = -1 + 1 ⇒ 2 = 0.
Now divide both sides by 2 and we would have 1 = 0.
Now add both sides by 1. This yields 2 = 1.
Therefore if 1 = -1 then 2 = 1.
