Select all of the following expressions that are equivalent to 0.25.

lora16 [44]

1. (0.5)2=1

2. (-0.2) + (-0.05) = -0.25

3. |-3 + 2.75| = 0.25

4. -(-0.25) = 0.25

5. 2x - 1.75x = 0.25x

So your answers are 3 and 4.

In the figure below, AMNO

NeX [460]

Given:

$\Delta MNO\cong \Delta PQR$

To find:

The length of QR.

Solution:

We have,

$\Delta MNO\cong \Delta PQR$

Then, $MN=PQ$ (CPCTC)

$10=4x-2$

$10+2=4x$

$12=4x$

Divide both sides by 4.

$\dfrac{12}{4}=x$

$3=x$

Similarity,

$MO=PR$ (CPCTC)

$2y+3=21$

$2y=21-3$

$2y=18$

Divide both sides by 2.

$y=9$

Now,

$x+y=3+9$

$x+y=12$

Therefore, the correct option is d.
