Answer:

- 6x + 12

Step-by-step explanation:

Expand the product of factors

= 2x² - 12x + 3x - 18 - 2x² + 3x + 30 ← collect like terms

= (2x² - 2x²) + (- 12x + 3x + 3x) + (- 18 + 30) ← simplify parenthesis

= 0 + (- 6x) + (12)

= - 6x + 12

This is the order you need to use to solve this problem: PEMDAS

(Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

So you start with P and make your way down to S

(2x + 3)(x - 6) - 2x² + 3x + 30    First multiply (2x + 3)(x - 6) (distribute)

(2x)x - (2x)6 + (3)x - (3)6 = 2x² - 12x + 3x - 18 = 2x² - 9x - 18

(2x²- 9x - 18) - 2x² + 3x + 30    Simplify by combining like terms

-6x + 12

What is 19a-3(a-6)=78
Ivan

Answer:

a = 3.75

Step-by-step explanation:

First distribute the -3 to (a - 6), which gives you the equation, 19a - 3a + 18 = 78. Then subtract the 3a from 19a, which gives you 16a + 18 = 78. Then subtract 18 from both sides and you get 16a = 60. Divide 60 by 16 and you get 3.75 as your a.

stellarik [79]

STEP - BY - STEP EXPLANATION

Given:

P(x)=x^3+4x^2+4

Step 1

Suppose x= -3, then

x+ 3

Step 2

Divide the polynomial by (x+ 3)

Step 3

Determine the remainder and quotient from the above.

Quotient = x²+ x - 3

Remainder = 13

ANSWER

Quotient = x²+ x - 3

Remainder = 13

Part A: Using computer software, a correlation coefficient of r = 0. 01 was calculated. Based on the scatter plot, is that an ac
sattari [20]

Part A: Based on the scatter plot given, the correlation coefficient of r = 0.01 is most likely accurate because the data points are far away from each other.

Part B: A casual relationship would be: the number of strawberries picked and the amount of fertilizers used.

<h3>What is Correlation Coefficient?</h3>

Correlation coefficient, r, is quantitative measure that measures the extent to which two variables are associated.

The closer the data points are on a scatter plot, the closer the value of r is to 1 or -1.

<u>Part A:</u>

The data points in the scatter plot are farther apart and the trend slopes upwards to the right, this means that the correlation coefficient, r, would be positive but very low.

Thus, based on the scatter plot given, the correlation coefficient of r = 0.01 is most likely accurate because the data points are far away from each other.

<u>Part B:</u>

A casual relationship would be: the number of strawberries picked and the amount of fertilizers used.
