Answer:

c sqrt( ( x2-x1) ^2 + ( (y2-y1) ^2)

Step-by-step explanation:

The distance formula is

d = sqrt( ( x2-x1) ^2 + ( (y2-y1) ^2)

It is the difference between the coordinates. It is based on the Pythagorean theorem

Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.

Anton [14]

Option C:

Area of the wall $=94\frac{15}{16}$ square feet

Solution:

Length of the wall = $12 \frac{1}{4}$ feet

Width of the wall = $7 \frac{3}{4}$ feet

Area of the wall = length × width

$$=12 \frac{1}{4}\times 7 \frac{3}{4}$

Convert mixed fraction into improper fraction.

$$=\frac{12 \times 4+1}{4}\times \frac{7\times 4+3}{4}$

$$=\frac{49}{4}\times \frac{31}{4}$

$$=\frac{1519}{16}$

Convert improper fraction into mixed fraction.

$$=94\frac{15}{16}$

Area of the wall $=94\frac{15}{16}$ square feet

Option C is the correct answer.

The formula for the eres of a triangle is A=2/1bh what is h equal to in terms of a and b

Kisachek [45]

Actually the formula for the area of a triangle is A = 1/2bh.

First step: multiply both sides by 2, to get rid of the 1/2.

2A = bh

Now divide both sides by b.

2A/b = h or h = 2A/b

Minchanka [31]

Answer:

Step-by-step explanation:

2k+10 | Both terms share the common factor two, so you can take it out (divide both terms by 2)

2(k+5) | Now if you use the Distributive Property to double check, you get 2k+ 10 again
