Mathematics

Maru [420]3 years ago
5 0
Perform the indicated multiplication:

2ax - 15 = 2x + 10 + 5x - 5

Group x terms together:  7x - 2ax = 5 - 15
                                          x(7-2a) = - 10
                                                    -10
                                           x = ----------
                                                   7-2a

Here, a cannot be 3.5, because the denominator 7-2a would be zero.

The figure below shows half circles at the ends of a rectangle with the demensions shown. Which is closest to the area of the fi
loris [4]
The closest answer is 95 square inches. Here is why.  You can find the area of the rectangle by multiplying the length by the width.  This would be 15 x 5 = 75 square inches.  The area of the whole circle that is created when you put both halves together would be found by multiplying 3.14 x 2.5 in (the radius) x 2.5 in.  This answer is about 20 square inches.  The combined area is approximately 95 square inches.
