Answer: -3
Step-by-step explanation:
-3x+ 7x+ 35= 5x + 38
You solve the distributive property on the left side and set it equal to the right
4x+35= 5x+38
-4x -4x
35= x+38
-38 -38
X=-3

Answer:
Right triangle.
Step-by-step explanation:
We are asked to determine whether the given side lengths are sides of a right triangle or not.
We know that side lengths of a right triangle are Pythagoras triplets. The square of the longest must be equal to sum of squares of other sides.
Let us check sides of our given triangle.
Since both sides of equation are equal, therefore, the given side lengths are sides of a right triangle.
Answer:
A: The triangle is a right triangle because 5 (to the 2nd power) + 12 (to the second power) = 13 (to the second power)
Step-by-step explanation:
25 + 144 = 169
169 = 169
To determine if it is a right angle, take all three numbers and multiply them by the second power. After you get all the numbers in their second power form, look at the first two numbers. If they equal the same as the third number, that is a right angle.

The round off value of 16311 is
what is rounding off?
Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
Given:
16311.
Now,
To round off nearest thousand focus on the place value of hundred place value.
Now, focus the value on hundred place value is less than 5 or greater than 5.
As, the number is less than 5 it will go towards previous number.
The round will lie between 16000 and 17000.
hence, the round off will be 16000.

You just need to take the numbers in the thousands place and left, and if the numbers on the right are greater than 500, you round up. In this case, 311 is less than 500 so you round down and get 16000.

let's take radius of the tennis ball as t
b = 3.6 t
volume of the basket ball vb = 4/3 pi b^3
volume of the tennis ball vt = 4/3 pi t^3
therefore
vb / vt = b^3 / t^3
= (3.6t)^3 / t^3
= 3.6^3
= 46.656
so the volume of the basketball is 46.656 times greater than the volume of the tennis ball.
