While doing a math problem in class, Jared's answer was different from his teacher's. So she had him come up and work the problem on the board. Here's Jared's work. .What was his mistake? A. There are not enough numbers after the decimal.
B. The sum of 7,294 and 3,647 is incorrect.
C. He left out the place holder under the 4.
D. He multiplied incorrectly

The correct option is B-He left out the place holder under the 4.

Step-by-step explanation:

Consider the provided multiplication.

Jared need to multiply 36.47 with 12

The correct multiplication should be:

36.47

×    12

 7294

36470

43764

Now consider the Jared's work he just left out the place holder under the 4.

Because it is not just 1×36.47 it is actually 10×36.47, so he needs to add a zero under the number 4.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

the answer is 489
