Answer: The required sum is $14x^2+17x.$

Step-by-step explanation: We are given to find the following sum :

$S=(8x^2+17x)+6x^2.$

To find the required sum, we need to the add the coefficients of the same powers of unknown variable x.

The summation is as follows :

$S\\\\=(8x^2+17x)+6x^2\\\\=8x^2+17x+6x^2\\\\=(8+6)x^2+17x\\\\=14x^2+17x.$

Thus, the required sum is $14x^2+17x.$

Answer:

<em>The actual distance between Rose Lake and the hiking trail is 7 miles.</em>

Step-by-step explanation:

The actual distance between Rose Lake and the main road is 3.5 miles and the scaled distance on the map is 2 inch.

Suppose, the actual distance between Rose Lake and the hiking trail is $d$ miles.

Given that, the scaled distance from Rose Lake to the hiking trail on the map is 4 inch.

So, <u>according to the ratio of "scaled distance" to the "actual distance"</u>, the equation will be......

$\frac{2}{3.5}= \frac{4}{d} \\ \\ 2d=4*3.5=14\\ \\ d=\frac{14}{2}=7$

Thus, the actual distance between Rose Lake and the hiking trail is 7 miles.

In △ABC, m∠A=44°, m∠B=48°, and a=25. Find c to the nearest tenth.

Nookie1986 [14]

Answer:

=36.0

Step-by-step explanation:

We use the sine rule to find the missing sides as follows;

Lets find the missing angle C by using the summation of interior angles in a triangle.

C=180-(44+48)

=88°

Then,

a/Sin A=c/Sin C

25/Sin 44=c/Sin 88

c=(25 Sin 88)/Sin 44

c=35.97

The side c=36.0 to the nearest tenth.
