ILL GIVE BRAINLIEST
Harrizon [31]

Answer:

a = -3/2 = -1.5

Step-by-step explanation:

(1+ax) (2+3x)³

Formula

(a+b)^3=a^3+3a^2b+3ab^2+b^3

(1 + ax) [ 2^3 + 3*2^2*3x + 3*2*(3x)^2 + (3x)^3]

(1 + ax) [ 8 + 12*3x + 6*9x^2 + 27x^3]

8 + 12*3x + <u>6*9x^2</u> + 27x^3 + 8ax + <u>36ax^2</u> + 54ax^3 + 27ax^4

coefficient of x^2 is zero

54x^2 + 36ax^2

54 + 36a = 0

36a = -54

a = -3/2

Which property is used 2(x+4)=2x+8
Elenna [48]

Answer:

Apply the distributive property

2x+2(4)=2x+8

Multiply 2 by 4

2x+8=2x+8

Move all terms containing x to the left and subtract 2x

2x+8-2x=8

Combine the opposite terms

2x+8-2x

Subtract 2x from 2x

0+8=8

8=8

All real number

Interpret the slope based on the chart.
bogdanovich [222]

Answer:

b. For 100 additional burglaries in California one expects to see an increase of about 3 burglaries in Hawaii.

Step-by-step explanation:

The slope gives the increase in the independent variable per unit increase in the dependent variable. Hence, a reasonable interpretation for the slope would be ;

the rate of change in the number of burglaries in Hawaii per 100 unit change in number of burglaries in California is 3.

Hence, for 100 additional burglaries in California, the rate of change in the number of burglaries in Hawaii is 3.

You are reducing a map of dimensions 2 ft by 3 ft to fit to a piece of paper 8 in. by 10 in. What are the dimensions of the larg
Alchen [17]

Answer:

6\frac{2}{3} in. by 10 in.

Step-by-step explanation:

2 ft by 3 ft, inches is:

2 * 12 = 24 inch

3 * 12 = 36 inch

24 * 36

Thus, to make 36 into 10, we divide 36 by 3.6 to get 10:

36/3.6 = 10

To keep ratio equal, we need to divide 24 by 3.6 to get:

24/3.6 = 6\frac{2}{3}

Thus, Third answer choice is right.
