Answer:
i think its B
Step-by-step explanation:
Cross mutiply and the answer would be 13/2 or 6.5
10x^3-8x^2-12x^2(x)
10x^3-8x^2-12x^3
-2x^3-8x^2
=-2x^2(x+4)
Answer:
The other angle measures are 40 and 40 degrees respectively.
Step-by-step explanation:
100 + 2x = 180
=> 2x = 80
=> x = 40
Since it is isosceles, the two remaining sides are equal, and therefore, they will have equal angles of 40 degrees.
Ok, really simple, honestly. Because 3(5x) = 15x. (3*5)(3*x) = 3*5 = 15*3 = 45x. Therefore, 15x and 45x do not correspond to each other at all, meaning that 3(5x) is not equivalent to (3*5)(3*x)!!!
