Answer:

50%.

Step-by-step explanation:

We are asked to write the closest benchmark for the percent for 48%.

We know that most common benchmark percentages are 0%, 10%, 25%, 50%, 75% and 100%.

Since our given percent is 48%, so the closest benchmark percent would be 50% as rounding up 48%, we will get 50%.

It would be 50% because it could be 25%, 0%, 75%, or 100% but 48 is closest to 50

1. Factor completely: 2a^2 + 6a + 18
USPshnik [31]

Answer:

2(a+3)(a+3)

5(x+1)(x-1)

3t(t-2)(t+8)

n(2+n)(2-n)

Step-by-step explanation:

Factor each expression

2a^2 + 6a + 18

2(a^2 + 3a + 9)

product =9 and sum =6

3 times 3 is 9

3 plus 3 is 6

2(a+3)(a+3)

2. Factor completely: 5x^2 − 5

GCF is 5

5x^2 - 5

5(x^2 - 1)

5(x+1)(x-1)

3. Factor completely: 3t^3 + 18t^2 − 48t

3t^3 + 18t^2 -48t

3t(t^2 + 6t -16)

product is -16 and sum is 6

-2 times 8 = -16

-2+8=6

3t(t^2 + 6t -16)

3t(t-2)(t+8)

4. Factor completely: 4n − n^3

n(4 -n^2)

n(2+n)(2-n)
