T(n)=6-1=5
that means all terms are 5 because n does not appear on the right hand side.
However, if T(n)=6n-1, then
first term = T(1)=6(1)-1=5,
but second term T(2)=6(2)-1=11...

Step-by-Step explanation:
Step 1: Define
8(x + 5) + 4 = 60
Step 2: Solve for a
1. Distribute 8: 8x + 40 + 4 = 60
2. Combine like terms: 8x + 44 = 60
3. Isolate x term: 8x = 16
4. Isolate x: x = 2
Step 3: Check
Plug in x to verify it’s a solution.
1. Substitute: 8(2 + 5) + 4 = 60
2. Add: 8(7) + 4 = 60
3. Multiply: 56 + 4 = 60
4. Add: 60 = 60
Answer:
8 × 10¹
Step-by-step explanation:
don't panic. just breathe deeply and then think logically.
0.002 ... what is that ? 2 10ths ? 2 hundredths ? 2 thousandths ? 2 tenthousandths ?
the 3rd position after the decimal point is for 1/1000.
and that means 10^-3. in the same way as 1000 is 10³.
so, it is 2 × 10^-3.
the other rounded number is then 4 × 10⁴.
now, we are multiplying both numbers
2×10^-3 × 4×10⁴
what do we do ?
we combine the same types of factors, like the basic constants : 2×4 = 8
and 10^-3 × 10⁴.
what hairball when we multiply the same base number with exponents ? we add the exponents :
10^-3 × 10⁴ = 10¹ = 10
because -3 + 4 = 1
and so, the result is
8 × 10¹
