Answer:
x=3
Step-by-step explanation:
Use the Pythagorean Theorem to write an equation.
x^2+y^2=z^2
Substitute values from the problem.
x^2 + 6^2 = 9^2
Solve for what you know.
x^2 + 36 = 81
Square root it.
x+6=9
Subtract 6 from both sides.
x=3
In the future, if you see a right triangle with an unknown side, and the other two sides are either 3, 6, or 9, you know that the other one is the missing value out of 3/6/9. This is called a 3/6/9 triangle.
Answer:
x > −3
Step-by-step explanation:
Let's solve your inequality step-by-step.
3(x + 2) > x
Step 1: Simplify both sides of the inequality.
3x + 6 > x
Step 2: Subtract x from both sides.
3x + 6 − x > x − x
2x + 6 > 0
Step 3: Subtract 6 from both sides.
2x + 6 − 6 > 0 − 6
2x > −6
Step 4: Divide both sides by 2.
2x / 2 > −6 / 2
x > −3
Answer:
x > −3
Hope this helps :)
On drawing , we have scale of 2 yard = 1 inch
so sides must be 6 inch, 7 inch, 8 inch and 9 inch !!
( just divide ) !!
if you got any problem, comment !!
