Calculate 1-2x = √ 6, x equals Calculate 1-2x = √ 6 x equals 1-2x = - √ 6 x equals

Calculate 1-2x = √ 6, x equals Calculate 1-2x = √ 6 x equals 1-2x = - √ 6 x equals

1-2x=√6
2x=1-√6
x=(1-√6/2)
1-2x=-√6
2x=1+√6
x=(1+√6/2)

2x-6 equals 12 and the next X + 2x equals 78

The first is 9, the second is 29

The solutions of 2x = 4x-8, X-6 of 2 = x 3 of 3 (2x-1) - 2 (1-x) = 0, 2x of 6 plus 3-x of 4 = 1 are 9 respectively. Write the calculation process

2x=4x-8
2x=8
x=4
2 X-6 = 3 x
x/2-x/3=6
x/6=6
x=36
3（2x-1)-2(1-x)=0
6x-3-2+2x=0
8x=5
x=5/8
Two sixths plus four (3-x) = 1
4x+3(3-x)=12
4x+9-3x=12
x=3

When what is the value of X, is the value of the algebraic formula 2x + 9x + 3 − 1x − 3 equal to that of 2 + 2x?

∵ 2x + 9x + 3 − 1x − 3 = (2x + 9) (x − 3) − (x + 3) (x + 3) (x − 3) = 2 (x − 5) (x + 3) (x + 3) (x − 3) = 2 (x − 5) x − 3. According to the meaning of the question, we get: 2 (x − 5) x − 3 = 2 + 2x, the two sides of the equation multiply x (x-3) to get 2x (X-5) = 2x (x-3) + 2 (x-3), the solution is x = 1

A 2 + AB = 15, B 2 + AB = 6

In the parallelogram ABCD, BF bisects ∠ ABC, intersects ad extension F, CE ⊥ BF, intersects Da extension e, and proves AE = DF

Intersection of AB and CE at point o
∵ BF bisection ∠ ABC, CE ⊥ BF
The triangle BOC is an equilateral triangle (three lines in one)
∴∠ABC=∠AFC=∠ECF=60
The cefo equilateral triangle
∴ED=CD
∵ triangle BOC is equilateral triangle, BF bisects ∠ ABC
∴∠ABF=∠30
∵ parallelogram ABCD, ∠ ABC = 60
∴∠FAB=120
∴∠AFB=30
∴∠AFB=∠ABC=30
∴AF=AB
∵ parallelogram ABCD
∴AB=AF=CD=ED
∴AE=FD

If the top and bottom of a trapezoid are extended by 3 meters, it will become a square. The area of the trapezoid is 15 square meters larger than that of the original trapezoid. What is the area of the original trapezoid?

According to the meaning of the title, it is a right angled trapezoid
If the top and bottom are extended by 3 meters, they will become a square. The area is increased by 15 square meters, and a right triangle is added. The height of the trapezoid is 15 × 2 △ 3 = 10 meters
Bottom = 10m
Top and bottom = 10-3 = 7M
Trapezoid area = (7 + 10) × 10 △ 2 = 85 square meters
