Answers

25 a² + 20 ab +  4 b²

for formula a^x+bx^ky^k+cy ^(2k ) find  u,v such that: u.v = a

and u+v = b  then  group according to (ax ^(2k) +ux^ky^k)+(vx^ky^k+cy ^(2k) )

(25a^2+10ab)+(10ab+4b^2)

factor out 5a from : 25a^2+10ab : 5a(2b+5a)

factor out 2b from : 10ab+4b^2: 2b(2b+5a)

5a(2b+5a) + 2b(2b+5a)

factor out : (5a+2b)

(5a+2b)(5a+2b)

Refine:

(2b+5a)^2

A fair number cube is rolled what is the probability that a number greater then 4 is rolled

Answers

Answer: 1/3

Step-by-step explanation: Probability is the likelihood that an event will happen.

So to find the probability of rolling a die and the number that appears will be greater than 4, it's important to understand that there are only 2 numbers that are greater than 4 on a die. The two numbers are 5 and 6.

We can find the probability of an event using the following ratio.

Number of favorable outcomes/total number of outcomes.

In this case, since we're asked to find the probability of landing on 5 or 6, the favorable outcomes are rolling a 5 and 6. Since there are two numbers greater than 4 on a dice, the number of favorable outcomes will be 2.

The total number of outcomes is all the numbers on the dice which is 6.

Now we have the fraction 2/6. Since 2/6 is not in lowest terms, we divide the numerator and denominator by 2 and we get 1/3.

1/3 is also equivalent to 33.3333333% which means it's unlikely to roll a 5 or 6.

What is f(3) for the quadratic functionf(x)=2x2 + x – 12?
F -3
G 3
H 6
I. 9​

Answers

Answer:

f(3) = 9

Step-by-step explanation:

Wherever you see an x on the right, put a 3 in for that x

f(x) = 2x^2 + x - 12

f(3) = 2*(3)^2 + 3 - 12

f(3) = 2*9 + 3 - 12

f(3) = 18 + 3 - 12

f(3) = 9
