The work of a student to find the dimensions of a rectangle of area 6 + 8x and width 2 is shown below: Step 1: 6 + 8x Step 2: 2(4) + 2(6x) Step 3: 2(4 + 6x) Step 4: Dimensions of the rectangle are 2 and 4 + 6x In which step did the student first make an error and what is the correct step? (1 point) Question 14 options: 1) Step 3; 2 + (4 + 6x) 2) Step 3; 2 + (4 ⋅ 6x) 3) Step 2; 2(4) + 2(4x) 4) Step 2; 2(3) + 2(4x)

Answers

Answer 1

Step-by-step explanation:

Hello,A=IxwStep 1:6+8xStep 2:2(3)+2(4x)Step 3:2(3+4x)Step 4:The dimension of the rectangle are 2 and 3+4x. As a result, Students makes the mistake at Step 2; 2(3)+2(4x). Hope it help!

Answer 2

Answer: (4)

Step-by-step explanation:

At step 2 the student rewrites 6 as 2*(4), and 8x as 2*(6x). This is incireect, since 2*(4) is actually 8, and 2*(6x) is 12x.

The correct way to do it is to rewrite 6 as 2*(3), and rewrite 8x as 2*(4x), which corresponds to the answer option (4)

Answer:Elimination will be easier

Step-by-step explanation:

you eliminate y by adding

Elimination would be a lot easier. The y’s cancel out leaving you with just the x’s. You would then combine all the leftover terms and solve for x. After you get x you plug it back into one of the equations and and solve for y. x=-2 and y=-7 or you can write it as (-2,-7)

Zachary traveled from city A to city B. He left city A at 7:30 a.m. and reached city B at 12 noon. Find his average speed if city B is 180 mi away from city A.

Please include the units after the answer!

Answers

Answer:

40 mph

Step-by-step explanation:

s = d/t

a to b's distance = 180 miles

7:30 - 12pm = 4.5 hours (time)

speed = 180 ÷ 4.5

speed = 40

40mph because it is 180 miles away and it took him 4.5 hours u divide 180 by 4,5

Find the values of x and y that make each quadrilateral a parallelogram. Show your work.

Answers

Step-by-step explanation:

A. to make the quadrilateral a parallelogram, we have:

7y + 5 = 8y - 4

112 = 10x - 8

<=> y = 5 + 4

120 = 10x

<=> x = 12

y = 9

B.we have:

17 = 4x + 5

63 = 8y - 1

<=> 12 = 4x

64 = 8y

<=> x = 3

y = 8

I NEED HELP ON THISSS!!!!!!!!

Answers

Answer:

1) x=0.3 y=2.2

2) x=6 y=9

Step-by-step explanation:

1/5 is 20% because 100 divided by 5 is 20. So 11 and 1.5 times 0.20 will get the amount for 20% aka 1/5. So 1.5, x, times 0.20 is 0.3. 11, y, times 0.20 is 2.2. For the next problem, 1:3 means that you multiply a side on E by 3 to get that same side on D. So 3, y, times 3 is 9. To get x, you reverse it. So 18, x, divided by 3 is 6.
