Answer:
x=10.5
Step-by-step explanation:
if the two triangles were ratios it would be like
19.3:7.2 to x:3.9
so 75.27 = 7.2x
whcih is 10.45 which is approximately 10.5
Answer:
Step-by-step explanation:
To solve:
x - 8 = -20
Simply add +8 to both sides of the equation.
It becomes :
x - 8 +8 = -20 + 8
Note that, -8 + 8 will cancel out, and results to zero.
Therefore the equation becomes :
x = -20 + 8
x = -12.
Hope this helped!
The left and right sides make up the parallel sides of the trapezoid. The top and bottom would be congruent but not parallel.
Answer:
No
Step-by-step explanation:
No because you have to look at the ones first
Lines are in the form y=mx+b, where m is the slope and b is the y-intercept. This line is thus y=9/4x-14, so C is correct. Multiplying by four, we get 4y=9x-56. Adding 56 and subtracting 4y, we see that 9x-4y=56, and multiplying by -1, we get 4y-9x=-56, so A is also correct. At this point, it is clear that B and D are incorrect, so A and C only are correct.
