Answer:
The solved expression is and
Therefore
Step-by-step explanation:
Given quadratic equation is
To solve the given equation by using completing the square :
Rewritting the above equation as below :
( it is of the form of heere a=x and b=3 )
Taking square root on both sides we get
Therefore and
The answer is no I think but not positive
Answer:
x = 6
Step-by-step explanation:
Using the rules of logarithms
• log x - log y ⇔ log ( )
• x = n ⇔ x =
Given
log(5x) - log(x - 3) = 1
log ( ) = 1, then
= = 10 ( cross- multiply )
10(x - 3) = 5x
10x - 30 = 5x ( subtract 5x from both sides )
5x - 30 = 0 ( add 30 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Answer:
For number 6
a) You can circle 4 right angles, 2 pairs of parallel sides, and all sides equal.
b) you could circle only one pair of parallel sides.
for 7 the answer is 405. Just times 15 by 27
Hope this helps!
