Answer:

$\huge\boxed{a^6b^3}$

Step-by-step explanation:

Because every term here is multiplied, simply count the number of 'a's and 'b's.

Hope it helps :) and let me know if you want me to elaborate.

deff fn [24]

Answer:

Step-by-step explanation:

$\frac{2x - 5}{5} + x - 2 = 3(x + 5)$

$\frac{2x - 5}{5} + x - 2 = 3x + 15$

$\frac{2x - 5}{5} = 2x + 17$

$2x - 5 = 10x + 85$

$-8x = 90$

$x = \frac{-45}{4}$

Answer:

74.31353

=74 m

Step-by-step explanation:

given that three locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side of the river. To find the distance AB across a river, a distance BC of 241 meters is laid off on one side of the river. It is found that the angle at point B is 108.6° and the angle at point C is 14.9°.

we have information about triangle ABC as side BC =241, Angle B = 108.6 and angle C = 14.9 degrees.

Hence this is an obtuse scalene triangle.

Angle ∠A = 56.5° (III angle)

Using sine formula we get

$\frac{AB}{sin 14.6} =\frac{BC}{sin 56.5} \\AB = 74.31353$
