5 0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x2−2x−8=0

Step 2: Factor left side of equation.

(x+2)(x−4)=0

Step 3: Set factors equal to 0.

x+2=0 or x−4=0

x=−2 or x=4

A building is 964 feet tall. Two people are standing on the ground directly west of the building. The
Lina20 [59]

Answer:

The distance from both of them = 1463.925  ft

Step-by-step explanation:

The building is 964 ft tall . 2 people are standing on the ground directly west of the building. The first person looks up at an angle of 62° to the top of the building while the second person did same at an angle of 26°. The distance between them can be computed below.

The illustration forms a right angle triangle . Using the SOHCAHTOA principle let us find the distance of the second person from the building

tan 26° = opposite/adjacent

tan 26° = 964/adjacent

adjacent tan 26° = 964

adjacent = 964/tan 26°

adjacent = 964/0.48773258856

adjacent = 1976.49290328 ft

The distance from the second person to the building = 1976.493 ft

Distance of the first person to the building

tan 62° = opposite/adjacent

tan 62° = 964/adjacent

adjacent tan 62° = 964

adjacent = 964/tan 62°

adjacent = 964/1.88072646535

adjacent = 512.567892122

distance from the first person to the building = 512.568 ft

The distance from both of them =  1976.493 ft - 512.568 ft = 1463.925  ft

Help ASAP!!!!! Please!!!
rjkz [21]

Answer:

300

Step-by-step explanation:

To find how many carrots, determine how many square units by finding the area. You can calculate the area by finding the area of the inside square 4 by 4 and then adding the area of each triangle on the side.

Area of square = 4*4 = 16 square units

Area of 2 triangles = 2(2*2*1/2)= 2(2) = 4 square units

16+4 = 20 square units.

15 carrots come from 1 square units so 15(20) = 300 carrots
