Answer:

15u^3 + 8u^2 - 6u + 13

Step-by-step explanation:

(7u^3 + 8u^2 + 8) + (8u^3 - 6u + 5)

= 7u^3 + 8u^2 + 8 + 8u^3 - 6u + 5

= 7u^3 + 8u^3 + 8u^2 - 6u + 5 + 8

*Now add the like terms

= 15u^3 + 8u^2 - 6u + 13

And that is all your can do!

Please help! Tysm! Picture of figure is attached.

Step-by-step explanation:

Notice that KM = 0.5BC, KL = 0.5AC

and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.

Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)

Perimeter of 3 small purple triangles

= 3 * [24cm * (1/4)]

= 3 * 6cm = 18cm.

Hence Total perimeter of shaded parts

= 12cm + 18cm = 30cm.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
