The answer would be A) The product of a constant factor of four and a factor with the sum of two terms.

The expression 4(y + 6) is the product of two factors: 4 and (y + 6).

4 is a constant factor; the value will remain as 4 regardless of the y value.

The second factor, (y + 6), represents a sum of two terms: y and 6.

Therefore, A is the correct answer.

Answer:

The answer is C

Step-by-step explanation:

Use the Pythagoras theorem which states that a2 = b2 + c 2

For easier understanding imagine a straight line along the x axis. At (0,0) we have Atlanta. Moving 21 units to our right we have Columbia. This is represented on the coordinate system by (21, 0). To go from Colombia to Charleston, which is located at (24, -11), we need to travel 3 units right along the x- axis to reach ‘24’ and ‘11’ units down along the y- axis to reach (24, -11). Starting from Colombia we can make an imaginary triangle with its perpendicular being the y- component and its base being the x- component, which as we have stated above is ‘-11’ and ‘3’ respectively

Now applying the Pythagoras theorem to calculate the hypothesis and hence the distance between Colombia and Charleston.

a, which represents the distance between Colombia and Charleston would be

a² = b² + c²

a² = (3)² + (-11)²

a = √[(3)² + (-11)²]

Hence the answer is C

Betty has a sister named Anne. Betty's sister, Anne, is 3 years younger than twice Betty's age.

chubhunter [2.5K]

The required equation is:

$a = 2b-3$

Step-by-step explanation:

Given

Let a be Anne's Age

and

b be Betty's age

Now we will onvert the given word problem in the form of equation step by step

"twice Betty's age." will be represented by $2b$

Then

"3 years younger than twice Betty's age." will be represented as: $2b-3$

Now

"Betty's sister, Anne, is 3 years younger than twice Betty's age."

$a = 2b-3$

Hence,

The required equation is:

$a = 2b-3$
