Answer:
36.575
Step-by-step explanation:
you need to find line ab you can do 
for the triangle and get the line you also need to get the squar root of it as it is still squared then devide by 2 to get the rades then times that by pi and there you go you have the area also sorry for spelling I love math not English
Answer: 
Step-by-step explanation:
Given equation: 
Since 5 is the greatest common factor of 65 and 60 in the given expression.
Therefore, the above expression can be written as
Hence, by factoring the side that contains the variable p we have the expression .
45+5.25n>108
-45 -45
————————
5.25n > 63
Divide both sides by 5.25
n>12
Answer:
2
Step-by-step explanation:
4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2. Please use
" ^ " to indicate exponentiation.
Rewrite 4x = 32 - x^2 in the standard form of a quadratic: x^2 + 4x - 32
Then the coefficients are a = 1, b = 4 and c = -32.
Find the discriminant. It is b^2-4ac.
Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.
Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.
So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."
Answer:
30
Step-by-step explanation:
you plug in k with 3 and j with 5
4 times 3 + 6(5 – 2) = 30
