Hi Jordyn! I think S is segment, B is base, and L is length. I hope this helped!
D. because 144/36=4 and the square root of 4 is 2
A negative sign under a square root means that the root is a not a real number.
A negative sign outside a square root means we can "cover it" and evaluate the square root.
When the sign is outside, you can do the root first, then apply the sign. Not so if the sign is inside.
Thus, √-49 is not real and -√64 = -8.
Answer:
6 times 10 to the 3rd power or 6 • 10^3
Step-by-step explanation:
On this problem, you are multiplying numbers that are in scientific notation.
3 • 10^7 multiplied by 2 • 10^-4.
To do it, you multiply the first part of each number (the mantissas) and you multiply the powers of ten part (the ordinates) of the two.
So.... 3 times 2 is....
right... 6
Then...
10 to the seventh power times 10 to the -4 power...
When you multiply the same base, you add the exponents...
So it is 10 to the "seven plus negative four" power.
That is 10 to the 3rd power.
So the final answer is
6 times 10 to the 3rd power.
Or
6 • 10^3
4x = 3/8
there are 2 ways to do this...
(1) 4x = 3/8....divide both sides by 4
x = (3/8) / 4
x = 3/8 * 1/4
x = 3/32 <==
or
(2) 4x = 3/8....multiply both sides by 1/4, cancelling out the 4 on the left
x = 3/8 * 1/4
x = 3/32 <==
