Answer: Rico is right.

(-1)(3x + 5)²

Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.

It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.

Then factor 9x² + 30x + 25 as

(3x + 5)²

What is 2x times x squared?
tresset_1 [31]

We want to multiply the monomial 2x by the monomial 2x^2.

Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: (a^m)(a^n)=a^{m+n}, (x^2)(x^4)=x^{2+4}=x^6. Also, is worth pointing out that the exponent of a variable with no exponent is 1: x=x^1.

Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so x=1x. Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.

Let's apply all of that to our multiplication:

(2x)(x^2)=(2x^1)(1x^2)=2*1x^{1+2}=2x^3

We can conclude that 2x times x squared is 2x cubed.

The probability of drawing a two and another 2 is 1/72

<h3>What is probability?</h3>

Probability is the likelihood or chance that an event will occur

  • Since the total number in the board game is 9, hence the probability of drawing a 2 will be 1/9

  • The probability of drawing the second 2 will be 1/8

  • Pr(drawing a 2, then drawing another 2) = 1/9 * 1/8

Pr(drawing a 2, then drawing another 2) = 1/72

Hence the probability of drawing a two and another 2 is 1/72
