Answer:
Correct option is:
9 ⋅ 104 is 3 times larger than 3 ⋅ 102
Step-by-step explanation:
9 ⋅ 104 = 3×3×104
3 ⋅ 102 = 3×102
104 is near to 102
Let 104 ≈ 102
3×104 ≈ 3×102
3×3×104 ≈ 3×3×102 = 3(3×102)
i.e. 9 · 104 ≈ 3(3 · 102)
Hence, Correct option is:
9 ⋅ 104 is 3 times larger than 3 ⋅ 102
Answer:
x= 13/2
Step-by-step explanation:
multiply 4x4+4x3-9x2-x+2=x-1
calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13
solution x=13/2
