For this case we have the following functions:

By definition of composition of functions we have to:
So:

By definition of division of powers of the same base we have to place the same base and subtract the exponents:

The question only supplied us with the mass of the new baby which is:

This mass is too bizzarre & unrealistic for
Answer:
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-4</u></em>
Step-by-step explanation:
First Expand :
6(x - 3)
= 6x - 18
Now you need to Simplify:
6x - 18 = -42
And now get the 6x by itself by doing this :
6x - 18 = -42
+18 +18
= > 6x = -24
And 6 x 4 = 24
But 6 x -4 = -24
So :
6x/6 and -24/6
= >> x = -4
Step-by-step explanation:
a. 12 + 4 = 16
1st left equation is matched to 4th right value
b. 3(4) + 7 = 19
2nd left equation is correctly matched to 2nd right value
c. 4(7) - 10 = 18
3rd left equation is matched to 1st right value
d. 1 / 2 × xy
1 / 2 × (4 × 7)
= 28 ÷ 2
= 14
4th left equation is matched to 3rd right value
