Sin time secant = sin(x)*1/cos(x) = tan(x)!!
You use the distributive property to simplify expressions.
4x+3(2x+1)
2 times 2x is 6x
3 times 1 is 3
4x times 2x is 8x
4x times 1 is 4x
total that is 6x+8x+4x+3=18x+3
Hope it helps!

Answer:
1.08 x 10³
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 1,080 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 1,080
New Number: 1.080
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 0 8 0
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 1.08 (Please notice any zeroes on the end have been removed)
b = 3
Now the whole thing:
1.08 x 10³
Step 4
Check your work:
10³ = 1,000 x 1.08 = 1,080
