Answer:
Step-by-step explanation:
21.4÷4.75
- First- you have to move the decimal placement two times to the right
- Second- you have to put the number 21.4 under the dividing box
- Third- put the number 4.75 out to the left of the decimal box
- Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
- Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
- Sixth- you keep on doing the fifth step until you get a reasonable answer
- Seventh- you write the answer down
- Eighth- there is no eighth step so you can stop reading this answer

Answer:
13x-10y
Step-by-step explanation:
Combine like terms;
10x+3x = 13x
-8y-2y = -10y
So it would give the equation of 13x-10y
I would’ve gone with the same choice so I think it’s right!!
You can check whether this is true using Pythagoras' Theorem. The Pythagorean Theorem:
a² + b² = c², where c is the hypotenuse of a right triangle.
Let's plug in the given values and check the validity of the statement.
a² + b² = c²
7² + 9² = 11²
49 + 81 = 121
130 = 121
This is false. Thus,
Answer:
False - a triangle with side lengths 7, 9, and 11 is not a right triangle.
