First off, in 5(n-3), there would be a hidden multiplication symbol:
5(n-3)
=5 x (n-3)
We then need to multiply 5 by the numbers in the bracket seperately:
5×(n-3)
=5×n + 3×5
=5n + 15
Therefore the answer is C. 5n - 15.
Here's another example similar to the above case:
3(y-1)
=3 × (y-1)
=3 × y + (-1) × 3
=3y + -3
Hope it helps!
By Green's theorem, the integral of along is
which is 6 times the area of , the region with as its boundary.
We can compute the integral by converting to polar coordinates, or simply recalling the formula for a circular sector from geometry: Given a sector with central angle and radius , the area of the sector is proportional to the circle's overall area according to
so that the value of the integral is
34 feet cuz 30+4=34 plus four not minus cuz he’s below sea level
Y α xz
y = kxz y = 72, when x = 6, and z = 4
72 = k*6*4
72 = k*24
24k = 72
k = 72/24
k = 3.
<span>y = kxz
</span>
<span>y = 3xz </span>
Finding y, when x = 3, z = 5.
y = 3xz
y = 3*3*5
y = 45
