B ; because like uk C equals (18)2 & that becomes into 36 so then u multiply it by pi and its 3.14 .
Answer:
Step-by-step explanation:
Based on the information provided we can create the following direct proportion equation...
D = 3.5x
In this equation, the variable D represents the distance that Brianna has walked while the variable x represents the number of hours she walked. In this equation, the constant of proportionality would be the 3.5 miles that Brianna walks per mile. This value affects the entire equation because it is multiplied by the number of hours Brianna walks which is directly proportional to the Distance she travels, as one value increases so does the other.
-3(x - 2) = 2(x - 7) remove the parentheses
-3x + 6 = 2x - 14. Move the terms
-3x - 2x = -14 - 6. Collect like terms. Calculate.
-5x = -20. Divide both sides.
Solution: x = 4
Answer:
Step-by-step explanation:
To simplify the expression 
first we need to raise every member of the denominator to the given exponent, number 4
Remember that 
where 'a' and 'b are natural numbers (any numbers you want
Where we can make some operations, remember that 
We have assumed that nor x, nor y equals 0 in any moment, since if that would happen, we ca not simplify anything bacause error math 0/0.
Answer:
(4 - a)^2 = 16-8a + a^2
(3x − 1)^2 = 9x^2−6x+1
Step-by-step explanation:
Multiply the left for each equation and they are the same.
