Step-by-step explanation: These two decimals are equal to each other because the zeroes in 7.400 don't change it's value.
So, after a decimal point, zeroes don't change the value of the decimal.
So we can simply drop the zeroes to see that 7.4 = 7.4.
Let the sides be a, b and c
Given:
b= 6cm
c= 10cm
To find: Side a
Solution:
By Pythagoras’ theorem:
a^2+b^2=c^2
a^2+6^2=10^2
a^2+36=100
a^2=100-36
a^2=64
a= root of 64
a=8cm
Answer:
[-18 10]
[5 -3]
Step-by-step explanation:
If you have a graphing calculator, you can go to 2nd x^-1, edit, put in your numbers, repeat for matrix b, and multiply them in that same menu.
Answer:
you can plug it back into the original equation to see if it fits the solution. if not then you have another solution you need to solve for.
