= 4 (6) - 4 (√2) + √2 (6) - √2 <span>√2
</span>= 24 - 4√2  + 6√2 - 2 
= (24 - 2)  +  (- 4√2  + 6√2)
= 22 + √2(- 4 + 6)
= 22 + √2 (2)
= 22 + 2√2

What is the value of the expression |a + b| + |c| when a = –3, b = 7, and c = –15?
nikdorinn [45]
We know:
|a|=  \left\{\begin{array}{ccc}a&if\ a \ \textgreater \  0\\0&if\ a=0\\-a&if\ a \ \textless \  0\end{array}\right\\\\|2|=2\\|0|=0\\|-3|=3

|a+b|+|c|
substitute a = -3; b = 7; c = -15
|-3+7|+|-15|=|4|+15=4+15=19

If it takes 20 N to move a box, how much power will be needed to move the box a distance of 5 meters in 5 seconds?
Dmitry [639]
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.

4. Find the H.C.F. of the following numbers. <br>6. 68,48 b. 64, 128<br>c. 24,54​
Goryan [66]

Answer:

Step-by-step explanation:

a)Factors of 6 = 1, 2, 3 and 6. Factors of 9 = 1, 3 and 9. Therefore, common factor of 6 and 9 = 1 and 3. Highest common factor (H.C.F) of 6 and 9 = 3.

he HCF of 68 is 68.....! bcoz 68 itself is a highest factor of 68.....!

48 are 2×2×2×2⇒16

b)64 = 1 × 2 × 2 × 2 × 2 × 2 × 2. 80 = 1 × 2 × 2 × 2 × 2 × 5.

Factors of 128 are 1, 2, 4, 8, 16, 32, 64, 128. There are 8 integers that are factors of 128. The greatest factor of 128 is 128. 3.

c.Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

54 = 2 × 27 = 2 × 3 × 9 = 2 × 3 × 3 × 3. 81 = 3 × 27 = 3 × 3× 9 = 3 × 3 × 3 × 3. 99 = 11 × 9 = 11 × 3 × 3. Factors common to all three numbers is 3 × 3.
