Answer:
5 * 1.15ⁿ
Step-by-step explanation:
The equation would be
a1(r)^(n-1)
Now put it all together
A15= 5(1.15)^(15-1)
Count the rest and add the towns each
A15= 35.38
35 villagers now
Now you will find the equation 1
an=5(1.15)^(n-1)
So it going to equal 5 * 1.15ⁿ
2 for the first box, 5 for the second, and 7 for the third.
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to
where
b is the diagonal of a face
h is the length side of the cube
we have
substitute
Answer:
Step-by-step explanation:
As with any equation involving fractions, you can multiply the equation by the least common denominator to eliminate fractions. Then solve in the usual way.
c) 1/a +b = c
1 +ab = ac . . . . multiply by a
1 = ac -ab . . . . subtract ab
1 = a(c -b) . . . . . factor out a
1/(c -b) = a . . . . divide by the coefficient of a
__
d) (a-b)/(b-a) = 1
a -b = b -a . . . . . multiply by b-a
2a = 2b . . . . . . . . add a+b
a = b . . . . . . . . . . divide by the coefficient of a
Please be aware that this makes the original equation become 0/0 = 1. This is why a=b is not an allowed condition for this equation. As written, it reduces to -1 = 1, which is false. One could say <em>there is no solution</em>.
__
f) bc +ac = ab . . . . . multiply by abc
bc = ab -ac . . . . . . subtract ac
bc = a(b -c) . . . . . . factor out a
bc/(b -c) = a . . . . . . divide by the coefficient of a
Answer:
x² + 13x - 56
Step-by-step explanation:
(x+7) (3x-8)
3x² - 8x + 21x - 56
combine like terms;
x² + 13x - 56
