Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!
Answer:
Length , time, mass, current, temperature, amount of mass, luminous intesity
m, sec, kg, A, K, mol, cd
Step-by-step explanation:
Seven basic SI units are used for measurement of
Meter for length
Second for time
Kilogram for mass
Ampere for current
Kelvin for temperature
Mole for amount of mass
Candela for luminous intensity
Symbols of these SI units are
m for meter
sec for second
kg for kilogram
A for ampere
K for kelvin
mol for mole
cd for candela
I think it’s A
Sorry if I’m wrong
First you substitute in the values so you have
V^2=(64)20
then you just simplify it
V^2=1280
V=the square root of 1280
V= about 35.7770876
or
V=the square root of 256 times <span>the square root of 5
V=16 times </span><span>the square root of 5
also V would typically be called velocity. it's very similar to speed but it is just easier to remember because it starts with a V</span>
