Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
11.3 feet.
12 squared (144) minus 4 squared (16) is equal to 128. The square root of 128 is approximately 11.3.
(a), (b), (d) and (f) are correct statements
36 tens or 360 is the answer.
Answer:
D
Step-by-step explanation:
f(x)=x³-2x²
f(i)=(i)³-2(i)²=i²×i-2(-1)
=-1×i+2
=2-i
