A: When they were distributing the 2, they didn’t distribute it to the 5. The correct answer would be 6x + 10
B: They didn’t distribute the 3 to the -3. The answer should be 6x^2 - 9
C: They didn’t distribute the -3 to the -4. The correct answer should be -9x + 12
D: The -20 should be a positive 20 because -4 x -5= 20. The correct answer should be -16x + 20
E: The 12 should be a -12 because -2 x 6= -12. The correct answer should be -8x^2 -12
F: They didn’t distribute the -9 correctly. The correct answer should be -36x^3 + 45x -54
Hope this helps!

Answer:
Step-by-step explanation:
The reduced side ratios, shortest to longest are ...
AC : AT : CT = 8 : 9 : 15
OD : OG : DG = 5 : 6 : 10
These are different ratios, so the triangles are not similar.
Answer:
n
Step-by-step explanation:
A function assigns the values. The range of the function will be between (-∞,10].
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
The given function f(x)=10-x² is a parabolic function that is negative, therefore, will open downwards. Now, the range of the function can be found as,
f(x)=10-x²
y=10-x²
y-10 = -x²
-y+10 = x²
-y + 10 = 0
y = 10
Thus, the range of the function will be between (-∞,10].
