For extra help the second answer is: 7a(3-a)
Answer:
-26
Step-by-step explanation:
so, the absolute value of 3 and 11 together is 14.
14-(15+3+2)2
14-(20)2
14-40
-26
Answer: a loss of 4 cents
<u>Step-by-step explanation:</u>
The probability of rolling a sum of 2, 3, 4, 5, or 6 is 
which earns $2.00
The probability of rolling a sum of 28, 9, 10, 11, or 12 is which loses $2.00
The probability of rolling a sum of 7 is 
which loses $0.25
Answer:
5x 1000
Step-by-step explanation:
From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"
y^2 + b^2 = a^2
y^2 + c^2 = x^2
y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2
a^2 - b^2 + c^2 = x^2
Now put in the values given for a,b,c to solve for x
(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x
