Note that √2 + √2 = 2√2

2/(2√2) = (√2)/2 = 0.707 (simplified)

0.707 is your answer

2(√2+√2)=2/(2√2)=1/(√2)≈0.707106781

You answer is 0.707106781 (Round to whatever number of decimals needed).

Solve for x.

Snezhnost [94]

L*w=20, so l=20/w
l=2w+3

20/w=2w+3
20=2w^2+3w
2w^2+3w-20=0

Slip and slide
w^2+3w-40
(w+8)(w-5)
(w+8/2)(w-5/2)
(w+4)(2w-5)

w= -4 or 5/2, but since width must be positive, it is 5/2

(5/2)*l=20
l=8

Final answer: Length= 8, Width= 5/2

Draw the line of reflection that reflects △ABC onto triangle Δ A'B'C'

lisov135 [29]

Answer:

Step-by-step explanation:

Coordinates of the vertex A → (-4, -6)

Coordinates of the vertex A' → (6, 6)

Since, y-coordinates are same opposite in notation,

Therefore, by the rule of reflection, line of reflection will be a line parallel to y-axis.

And points A and A' will be equidistant from the line of reflection.

Midpoint between A and A' = $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

= $(\frac{-4+6}{2},\frac{-6+6}{2})$

= (1, 0)

Therefore, x = 1 will be the line of reflection.

Answer:

sometimes

Step-by-step explanation:

|x| =x

We can look at 3 case, when x>0, x=0, and when x<0

If x>0

|3| =3

3 = 3

True

x=0

|0| =0

0 = 0

True

x<0
