Answer:
X= 19
Step-by-step explanation:
If you take 4 away from 19, it equals 15, the perimeter is all sides of the square. Which is 4 sides, 15 x 4 = 60 or 15+15+15+15. The formula for perimeter is all the sides added together.
Answer:
what is the perimeter of a 12 cm and 4cm is16cm
Answer:
30
Step-by-step explanation:
Adjacent angles of a parallelogram add up to 180 degrees, meaning that (3x)+(x+60)=180 degrees. You can use this to set up the following equation:
3x+x+60=180
4x=120
x=30 degrees. Hope this helps!
The answer is D. (3,-39)
Just plug the numbers into the formula to find the Parabola.
<span>f(x) = ax</span>

<span><span>+ bx + c
</span>
Then find X:
