Answer:

Step-by-step explanation:

divide by the prime numbers 2, 3, 5, 7 until 1 is reached. The prime factorisation is the product of the prime numbers we have divided by.

Note if a particular value does not divide by a prime, move on to the next prime.

divide 700 by 2

700 ÷ 2 = 350 ← divide by 2 again ⇒ 2

350 ÷ 2 = 175 ÷ now divide by 5 ⇒ 2

175 ÷ 5 = 35 ← divide by 5 again ⇒ 5

35 ÷ 5 = 7 ← now divide by 7 ⇒ 5

7 ÷ 7 = 1 ← factored when 1 is reached ⇒ 7

700 = 2 × 2 × 5 × 5 × 7 → D

P(x)=(x-2)(x-3)(x+7) find the constant term

hram777 [196]

Short method: multiply constants
$= ( - 2) \times ( - 3) \times (7) \\ = 6 \times 7 \\ = 42$

Long mothod: expand it
$= ( {x}^{2} - 5x + 6)(x + 7) \\ = ... \\ = ... + 42$

Very important!! Solve the inequality 6r + 30 ≥ 12 or -r > 12 (the question is important for high school application c:)

Fofino [41]

First simplify the one inequality, 6r + 30 greater than or equal to 12 just divide by 6 then subtract 30 from both sides of the inequality. You should get r is greater than or equal to -3. For this one you need to reverse the inequality symbol then divide both sides by -1 to get a positive r, and you get r is less than -12. It's not A because there's two solutions, and it's not D for the same reason. It's not C because r isn't greater than -12. In conclusion it's B because it correctly represents the solutions that make the inequality true. I hope this helps you on your high school application :)
