Answer:

each side 5

Step-by-step explanation:

with 2 equal internal base angles, we know this is an isosceles triangle

this being isosceles also tells us that the 2 opposite sides are also equal

Therefore: x + 2 = 3x - 4

solving for x

x - 3x = -4 -2

-2x = -6

x = -6 ÷ -2

× = 3

substituting x:

x +2 = 3 + 2 = 5

3x-4 = 9 - 4 = 5

A warehouse's rectangular ceiling measures 12 meters by 18 meters, and is covered by acoustic tile squares which are one meter o

asambeis [7]

The first thing to do is find the rectangular warehouse area.
We have then:
A = (12) * (18) = 216
A = 216 m ^ 2
We now look for the area of each acoustic tile square:
A '= (1) ^ 2 = 1
A '= 1 m ^ 2
We look for acoustic tile squares number:
N = (A) / (A ')
N = (216) / (1)
N = 216
Finally we look for the total weight:
W = (1/4) * (216)
W = 54 Kg
Answer:
The total weight of the tile required to cover the ceiling is:
W = 54 Kg

Minchanka [31]

Answer:

$70\ \text{kilometers}$

Step-by-step explanation:

The scale of the map is 1 centimeter distance on the map represents 20 kilometers of actual distance.

The distance between the two cities is 3.5 centimeters on the map

$1\ \text{centimeters on the map}=20\ \text{kilometers of actual distance}$

So,

$3.5\times 20=70\ \text{kilometers}$

So, the distance between the two cities is $70\ \text{kilometers}$ .

4x² - 8x - 4 .

To Find :- 

To find the factorised form .

Answer :- 

Taking the given expression,

→ 4x² - 8x + 4

→ 4x² - 4x -4x + 4

→ 4x ( x - 1 ) -4( x -1)

→ (4x - 4)(x-1)

Hence the required answer is (4x - 4)( x - 1) .
