Answer:
x = 14
Step-by-step explanation:
Since they are similar triangles, their sides are proportional
12 : 15 :: 8 : x - 4
Product of extremes = Product of means
12 × ( x- 4 ) = 15 × 8
12x -48 = 120
12x = 120 + 48
12x = 168
x = 168/12
x = 14
-2/3 / -15
Find the reciprocal of -15 and multiply:
-2/3 * -1/15
Multiply the numerators and denominators together:
2/45
Answer:
C. (4,-7)
Step-by-step explanation:
To answer this question, I just graphed the two equations. Then I found where they intersected.
It would be 2u3+4u2-2u-4u2-8u+4= 2u3-10u+4
