Factored completely, the expression 16k^2 + 16k + 4 is equivalent to
sergeinik [125]
16k^2 + 16k + 4

We can first start off by dividing every term by 4:

4 (4k^2 + 4k + 1)

to factor, you find which two number you can multiply with each other to get the middle term. So 2 and 2 to get 4. Substitute that into the equation

4 (4k^2 + 2k + 2k + 1)

the first two terms become a group and the last 2 terms become a group. Factor like terms out of the two groups.

4 (2k (2k + 1) + 1 (2k + 1))

4 (2k + 1)(2k + 1)

Please help me 20 points (just the ones with circles)
Elena-2011 [213]

Answer:

1. 5 is a solution to the inequality

2. 8 is a solution to the inequality

3. q=20 is a possible solution to the inequality

4. t=28 is not a possible solution to the inequality

Step-by-step explanation:

1.

1+f<7

subtract 1 from both sides of the inequality;

f<7-1

f<6

The value of f should therefore be strictly less than 6. From the alternatives given only the number 5 meets this condition and is thus a solution to the inequality.

2.

g-3>4

add 3 to both sides of the inequality;

g>4+3

g>7

The value of g should therefore be strictly greater than 7. From the alternatives given only the number 8 meets this condition and is thus a solution to the inequality.

3.

q-2>16

add 2 to both sides of the inequality;

q>16+2

q>18

The value of q should therefore be strictly greater than 18. Consequently, q=20 is a solution to the inequality since;

20>18

4.

t-7<10

add 7 to both sides of the inequality;

t<10+7

t<17

The value of t should therefore be strictly less than 17. Consequently, t=28 is not a solution to the inequality since;

28 is not less than 17.
