The side length was multiplied by 5.
The side length was increased by 10.
The side length was multiplied by 10.

Answers

Answer 1
Answer: Given:
a square with an area of a² is enlarged to a square with an area of 25a².

The side length of the smaller square was changed when The side length was multiplied by 5.

Area = (1a)² = a²
Area = 1a * 5 = 5a ⇒ (5a)² = 25a²
Answer 2
Answer:

the correct answer is B

What is the length of the missing side of the quadrilateral shown if the perimeter is 5x^2+2x+1?

Answers

 I am thinking that the quadrilateral is not given to be a rhombus.

The perimeter is the sum of the 4 sides.

Adding 2x^2 + x -1 to 3x^2 -5x and then that sum to 4x^2 gives

9x^2 - 4x - 1 as the sum of the three given sides.

Subtract that from the given perimeter to get the missing side length.

5x^2 + 2x + 1 - (9x^2 -4x -1) =

-4x^2 + 6x + 2

If u rotate an object around a given point what information will you need?

Answers

Answer:

A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).

Step-by-step explanation:

Please answer ASAP! An explanation is a MUST REQUIREMENT in order to receive points and the Brainliest answer. Thank you.

(\sqrt[3]{x^(2)})^(6)=x^{(2* (1)/(3))*6}=x^{ (2)/(3)*6 } =x^(4)
the cube root of x^2 is x^2/3
because it is in the bracket and the power of 6 sign is outside you multiply its index (2/3) by 6 and you have x^4
so the answer is the second one, x^4

hope this helps :)
