Hendrick wants to enlarge a photo that is 4 inches wide and 6 inches tall and large photo keeps the same ratio how tall is the enlarge photo if it is 12 inches wide

18 inches

Step-by-step explanation:

We have that,

Length of the photo, = 6 inches and Width of the photo, = 4 inches.

Now, the photo is enlarged with the new width i.e. is 12 inches.

Let, the length of the enlarged photo i.e. be x inches.

Since, the ratio between length and width remains same, we have the relation,

i.e.

i.e.

i.e.

i.e.

i.e.

Hence, the length of enlarged photo is 18 inches.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
