Answer:
=1/10
Step-by-step explanation:
Answer:
After solving we get
Step-by-step explanation:
We need to solve the equation:
Solving:
Multiply 4x with terms inside the bracket
We need to solve above equation to find value of x
Using quadratic formula for finding value of x:
We have a=180, b=-28 and c=-57
Values of x are
So, After solving we get
Step-by-step explanation:
an=-3n+50
Let n=15 -----because we need to find 15th term
a15=-3×15+50
=-45+50
=5
88°, 34°, 58°. The three interior angles of any regular triangle has a total of 180°.
88+34+58=180
Answer:
a = √[(c — b)(c + b)]
Step-by-step explanation:
a^2 + b^2 = c^2
We can make "a" the subject by doing the following:
a^2+ b^2 = c^2
Subtract b^2 from both side:
a^2 = c^2 — b^2
Take the square root of both side
a = √(c^2 — b^2)
Since we have difference of two squares, we can simplify further as:
a = √[(c — b)(c + b)]
