I can’t tell what’s going on
The answer is D. 3x^3+4x^2-11x+3
Let the breadth be x
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer
Answer:
W = - 14
Step-by-step explanation:
13W - 2(4W + 1) = W - 58
13W - 8W - 2 = W - 58
13W - 8W - W = 2 - 58
4W = - 56
W = - 56 : 4
W = - 14
<span>c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
