Answer:

Option C. (3x + 2)(3x - 1) is the answer.

Step-by-step explanation:

The given expression is 9x² + 3x - 2 and we have to factorize the expression given.

9x² + 3x - 2 = 9x² + 6x - 3x - 2

= 3x(3x + 2) - 1(3x + 2)

= (3x + 2)(3x - 1)

So the factorized form of the expression is (3x + 2)(3x - 1).

Option C is the correct answer.

Answer:

Choice C is the answer.

Step-by-step explanation:

We have given an expression.

9x²+3x-2

We have to factorize given expression.

Split the middle term of above expression so that the sum of two terms should be 3 and their product be -18.

9x²+6x-3x-2

Making groups and taking common , we have

3x(3x+2)-1(3x+2)

Taking 3x+2 as common, we have

(3x+2)(3x-1) which is the answer.

The Cowboys High School Band Boosters are selling candy bars and chips at the basketball tournament to raise money for their ban
masya89 [10]

Answer:

They have 425 candy bars ready to sell.

Step-by-step explanation:

Let,

x be the number of candy bars ready to sell

y be the number of chips ready to sell

According to given statement;

x+y=575     Eqn 1

x+0.5y= 500     Eqn 2

Subtracting Eqn 2 from Eqn 1

(x+y)-(x+0.5y)=575-500

x+y-x-0.5y=75

0.5y = 75

Dividing both sides by 0.5

\frac{0.5y}{0.5}=\frac{75}{0.5}\\y=150

Putting y=150 in Eqn 1

x+150 = 575

x = 575-150

x = 425

Hence,

They have 425 candy bars ready to sell.

Which of these lines could possibly intersect the graph of a function at more than one point? Select three that apply.
Vera_Pavlovna [14]
According to Vertical Line test, a vertical line only intersect the graph of a function at one point. Among the choices given, x = 4 is a vertical line. So this line cannot intersect the graph of a function at more than one point. The other three would apply. So the answer choices are A, C and D.

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression (√2)π/(√5) is 2.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of the expression (√2)π/(√5) can be written as,

\dfrac{\sqrt2 \pi}{\sqrt5}\\\\= \sqrt{\dfrac25}\pi\\\\=\sqrt{0.4} \times \pi\\\\

= 0.6324 × π

= 1.9869 ≈ 2

Hence, The value of the expression (√2)π/(√5) is 2.
