Answer:
I can't do the area but area of a triangle is
A of triangle = h×b over 2
h = hieght of the triangle
b= base of the triangle
The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.
75 is the median
And 79 is the mode
If you meant tens place it's 330 if you meant tenths place it's 325.5
The answer is B, because if you draw the baseboards on the scale drawing, you'll get nineteen baseboards. 19 x 4,19 = 79,61
