4 0

Answer:

Step-by-step explanation:

→ –36 – ( –40 )

Whenever there is sign of subtraction before the brackets, signs of the numbers inside the brackets get changed when we removed the brackets.

( – ) × ( – ) = ( + )

→ –36 + 40

→ 4

$\therefore$ 4 is the required answer.

I need help with this question

Sonbull [250]

= 4 (6) - 4 (√2) + √2 (6) - √2 √2
= 24 - 4√2 + 6√2 - 2
= (24 - 2) + (- 4√2 + 6√2)
= 22 + √2(- 4 + 6)
= 22 + √2 (2)
= 22 + 2√2

If M is the midpoint of PQ and X is the midpoint of PM then PX = a PQ Which statement is True? a is equal to 1 a is equal to 1/2

garik1379 [7]

Answer:

D. a is equal to $\frac{1}{4}$

Step-by-step explanation:

Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.

Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.

Then;

PX = aPQ

⇒ = a x 8

= 8a

Therefore, a must be equal to $\frac{1}{4}$ , so that;

PX = 8a

= 8 x $\frac{1}{4}$

= 2 units

Thus, a is equal to $\frac{1}{4}$ is the correct option.
