Answer:
Step-by-step explanation:
Given
Required
Determine the roots
To get the root of the function, then f(b) must be 0;
i.e. f(b) = 0
So, the expression becomes
Add 75 to both sides
Take square roots of both sides
Reorder
Expand 75 as a product of 25 and 3
Split the expression
The options are not clear enough; however the roots of the equation are
If you are saying that the hypotenuse is 10 cm the you have to solve the following equation using the Pythagorean theory.
4^2 + b^2 = 10^2
16 + b^2 = 100
16 - 16 + b^2 = 100 - 16
b^2 = 84
Find 
Answer:
you multiply the quotient times the divisor and your awnser should be the same as the dividend
Step-by-step explanation:
4a - 3b
4(5) - 3(- 2)
20 + 6
26
26 is your answer.
You multiply it with the same number you use for the denominator.
in this case 3/4 and 7/10
you find the LCM of the denominator is 20
so for 4 to become 20 you multiply by 5 then for the numerator 3 also multiply by 5, so you get 15/20
its the same also with 7/10, you multiply both the numerator and the denominator by 2 and get 14/20
hope it help... :)
