Let's say, the total sales is "x"... .so hmm on Plan A, he gets 350 plus 7% of "x", well, 7% is just (7/100) * x or 0.07x
now, on Plan B, he gets 436 plus 5% of "x", 5% of "x" is (5/100) * x, or 0.05x
he's better off with A, only if A is greater than B, namely,
A > B
and surely you know how much that is.
The options are;
<span>a)4x+12
b)8x+24
c)2x^4+24
d)4x^2+24x+35

dimensions of the photograph
length - 7 inch
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides
Perimeter = 2(7 + 2x) + 2(5 + 2x)
= 14 + 4x + 10 +4x
= 24 + 8x
correct answer is b
Since we know a circle has 360 degrees, the sector bounded by a 90 degree arc will be a quarter of circle (360/90 = 4). Then, to calculate the area of that sector, we can calculate the total area of the circle of radius 10, and then divide it by 4.
The area of a cirlce of radius r is:

Then, the area of the sector would be:
