Answer:

A. The area of a rectangle is equal to all the areas of the small rectangles. The dimensions of the small rectangles are 2a, 3a, and 4a. If you add those areas up, 2a+3a+4a equals the area of the large rectangle.

B. The area of a rectangle equals the width and height. The height of the large rectangle is already shown in the picture, a. The width is seperated into three portions, 2, 3, and 4. To find the total width, add 2+3+4. Now, multiply the width by the height to calculate the area. (2+3+4)a

Answer:

4th option / (-8,-4)

Step-by-step explanation:

If you graph the point (8,-2) and you translate if 6 units down and you look at your new point then that's how you get the answer.

Answer:

-4

Step-by-step explanation:

-4b + 2 = 18

subtract 2 from 2

subtract 2 from 18

-4b = 16

divide -4 by -4

divide 16 by -4

b = -4

Answer: The pack of 20.

Step-by-step explanation:

It is because a pack of 20 sells for 2.50 for each pencil, and the pack of 12 sells for 2.51 per pencil, so that means the pack of 20 is cheaper.

Answer:

Yes

Step-by-step explanation:

If they are the same linear equation, there would be infinite solutions. IT would look like:

Answer: x = 1

3x + 4 = 7

subtract 4 from both sides

3x = 3

x = 3/3 = 1

Answer: 7/8

Step-by-step explanation:

You can change all the fractions to have equivalent denominators.

The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.

1 1/4 = 1 2/8 = 10/8.

3/8 = 3/8.

Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.

10/8 - 3/8 = 7/8.

Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.

Answer:

3.1415967382

Step-by-step explanation:

A unit rate is a rate in which the second quantity, or denominator, in the comparison is 1 unit. You can find the unit rate by dividing the first quantity in a relationship by the second quantity.

The most common second quantity in rates, from personal experience, is the denominator in a fraction, like the 1 in 50/1. This is because the denominator is seen as the one specifying the unit. For example, in the rate "a car goes 50 miles per hour," the numerator would be the distance the car is traveling, which is 50, whilst the denominator would be the time the car takes to drive a certain distance - in this case, 1 hour. The first quantity is 50 miles and the second quantity is 1 hour. We can divide the first quantity by the second to get the fraction 50/1, which is a unit rate because the denominator (second quantity) has a value of 1. This also applies to values such as 90/3, where we would be trying to simplify the fraction to get a denominator value of 1.

The Equivalent Expression is 12 + 12x + 6y.

Therefore, option A is correct.

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the expression: 6(2 + x + x + y)

Using Distributive property

a x ( b + c + d) = ab + ac + ad

So, the simplified expression is

= 6(2 + x + x + y)

= 6(2) + 6(x) + 6(x)+ 6(y)

= 12 + 6x + 6x + 6y

= 12 + 12 x + 6y

So, the Equivalent Expression is 12 + 12x + 6y.

Answer:

Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees

Step-by-step explanation:

Hope this helped :)

Answer:

A

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

180 degrees = Triangle

Angle 1 = 60

angle 2 = 90 because it's a right triangle

Angle 3 = 180 - (60+90) = 30

60 + 90 = 150

180 - 150 = 30
