The answer to this question is A≈12.57
i'm doing cross-multiplication for this problem:
multiply 18 · 12, which is 216
divide 216 ÷ 10, which is 21.6
, is the final answer
Answer:
f(x)=-3x+14
Step-by-step explanation:
y +1=-3(x–5)
y +1=-3x+15
y= -3x+15-1
f(x) = -3x + 14
If n is odd then its cube is also odd because odd times odd is odd. When we add 5, an odd number, we get an even number.
If n is even, its cube is also even so adding an odd number makes the sum odd. So if the expression is odd, n must be even.
So you can see the right angle is 90
