Four students factor the expression 16x+12. The table shows the students’ responses.

Answers

Student four was correct

student 4 factors the expression correctly.

What is algebraic Expression?

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

The expression 16x + 12 can be factored out by finding the greatest common factor (GCF) of its terms,

which is 4, and factoring out 4:

16x + 12 = 4(4x + 3)

Thus, the factored form of 16x + 12 is 4(4x + 3).

Therefore, student 4 factors the expression correctly.

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.

A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.

Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.

Answers

Answer:Part A:8 Part B:$1

Step-by-step explanation:

Part A: 7 dollars

- The graph shows that 2 bushels is 14 dollars, because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.

- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.

- 7 can be known as the slope and rate of change.

Part B:2 dollars

- The years before show 2 bushes was 10 dollars

-so you would divide 10 by two you would get five To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.

-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

Answers

Answer:

this is algebra remember algebra rules and thing really hard

Step-by-step explanation:

The formula for the height of the trapezoid will be h = 2A/(c+ d).

What is surface area?

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given a trapezoid with side lengths c and d and perpendicular distance as h

So, the area formula will be

A = (1/2)h(c + d)

Multiply both sides by 2

2A = h (c + d)

Divide by c + d into both sides

2A/(c + d) = h

Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

Answers

Answer:

3.33~

Step-by-step explanation:

Since 1 inch represents 1.5 feet, you'll divide 5 inches by 1.5. And get 3.33 repeating

Answer:

7.5 feet

Step-by-step explanation:

REASON

According to the given scale, 1 inch on the drawing represents 1.5 feet in the actual house.

Therefore, to find the length of the bedroom window in feet, we need to multiply the length on the drawing (5 inches) by the scale factor (1.5 feet/inch):

5 inches * 1.5 feet/inch = 7.5 feet

Hence, the bedroom window will be 7.5 feet long in the actual house.
