Answer:
C
Step-by-step explanation:
First we distribute (-2,3) into the equations so 2x+4y becomes 2(-2)+4(3) so that's -4+12 which is 8 making equation 1 correct.
Then x+2y becomes (-2)+2(3) which is 4 so the second equation is correct as well therefore the answer has to be C because of process of elimination
The log of 1 is zero. Therefore:
log 3x - log 1 = log 3x.
So in finding the area of the square where the part of the yard that is not covered, first is to calculate the are of both then subtract the two and the are for the circle is pi*r^2 so it means pi*(4x)^2 then for the are of square the formula is A^2 and its (20x)^2, and i think the best answer would be 20X^2-(pi*4x^2)
