Answer:
Carbon has 6 protons while oxygen has 8 protons.
Step-by-step explanation:
Let x be the number of protons in carbon and y be the number of protons is oxygen.
ATQ: 2x+y=20 and x+2y=22. Solving it, we will get x=6 and y=8
I’m pretty sure that the answers
C
Answer:
231cm²
Step-by-step explanation:
find the area of the rectangle. 12 x 11=132
find the area of the triangle. 9 x 11=99
add the two areas together. 99 + 132=231
Try sketching the cardboard piece labeling each side. when folded, the height of the box is x, the length is now (13 - 2x), the width is now (6 - 2x) after cutting out the squares from each corner.
volume = length*width*height
V(x) = x(13 - 2x)(6 - 2x)
Pick any 2 data points from the list, say (6,13) and (5,11)
compute m, slope using the slope fornula m= y2-y1/x2-x1 = 13-11/6-5=2/1=2. pick any point and write your equation in slope intercept form
y-11=2(x-5)
y-11=2x-10
y=2x+1. answer B
