It will have 15 protons because the atomic number will always equal the number of protons and vice versa
Answer:
<h2>50</h2>
Step-by-step explanation:
Put h = 7 to the expression 5 · (h + 3):
![5\cdot(7+3)=5\cdot10=50](https://tex.z-dn.net/?f=5%5Ccdot%287%2B3%29%3D5%5Ccdot10%3D50)
0 because 0 times anything is 0
I'm not sure about the second image.
But the first one is telling you to translate x, 3 units left, and translate y, 4 units up.
(-6, 0) will turn to (-9, 4)
I subtracted 3 from -6 and added 4 to 0.
