Answer:

100-4q^{2}

Step-by-step explanation:

\\(10-2q)(10+2q)\\=(10)(10)+10(2q)-2q(10)-(2q)^{2} \\=100+20q-20q-4q^{2} \\=100-4q^{2}

Answer:

100 - 4q²

Step-by-step explanation:

(10 - 2q)(10 + 2q)

each term in the second factor is multiplied by each term in the first factor.

10(10 + 2q) - 2q(10 + 2q) ← distribute parenthesis

= 100 + 20q - 20q - 4q² ← collect like terms

= 100 - 4q²

pshichka [43]

Answer:

x = 3 \frac{(y - 6)}{2}  \\  \\ x =  \frac{ - 5 - y}{3}

Step-by-step explanation:

2x =  - 18 + 3y \\ 2x = 3y - 18 \\ x =  \frac{3y - 18}{2}  \\ x =  \frac{3(y - 6)}{2}  \\  \\ 3x =  - 5 - y \\ x =  \frac{ - 5 - y}{3}

HELP WILL GIVE BRANLIEST!!
antoniya [11.8K]

Answer:

on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.

Now

On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)

But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2

In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together

So our required answer is

p(even number)× p(tails)= 1/2 × 1/2 = 1/4

Step-by-step explanation:
