Answer: C
Step-by-step explanation: i’m doing the test too
The correct answer is 6 × (7 + 2) - 1 = 53. This is because in the Order of Operations, multiplying comes first. So to make sure you get the right answer, you have to put the 7 + 2 in parentheses to get 6 × 9 - 1 and not 6 × 7 + 1.
A = (9/6)*10 mm = 15 mm
b = (35/10)*6 mm = 21 mm
The ratio in parentheses is the ratio of corresponding sides in the respective rectangles, so is the scale factor. The unknown dimension is that scale factor applied to the corresponding known dimension.
