Answer:

Hello there! Your answer would be D and A

Step-by-step explanation:

I cant see A but as I go through all the others I get A.  You know that a rectangle has 4 sides like a quad. but each of the opposite sides has to be equal. So you can see that D is without needing to look closer. It gets harder after that.  We know that C is not one because none of the sides are even. Now there is B and A if you turn your computer/paper you will see that B is a square. So because of that, I think that A is a rectangle. :]

The shapes that present the rectangle will be B and D.

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.

If the opposite sides of the quadrilateral are parallel then the quadrilateral is known as a parallelogram.

And if all the angles of the parallelogram will be equal. Then the parallelogram will be known as a rectangle.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The shapes that present the rectangle will be B and D.

ITS B UAU

The answer is b becasue its subtraction

Step-by-step explanation:

Polynomials are closed under an operation if it produces a polynomial.

5x⁴, x² + 2x + 1 and x³ - 10x³ + 28x - 15

are all polynomials of x.

x - 3 + (-3)/(x - 2) is not a polynomial because x can be found in the denominator of a fractional term.

The answer is Option A.

What's the problem??????

Answer:

40 km/hr

Step-by-step explanation:

Given that:

Total distance covered in 3 hours = 60km

Speed during first 40 km = 16km/hr

Hence, time spent during the first 40 km ;

Recall:

Time = distance / speed

Time = 40 / 16

Time = 2.5 hours

Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours

Speed = distance / time

Speed = 20 / 0. 5

Speed = 40 km / hr

So let’s say I have 5 as well

triple of 5 is 5,10,15

15+5=20

my friend has 20 comic books

and I have 5

Step-by-step explanation:

brainlyest please

The expression represents the number of comic books a friend has is F = 3c + 5.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given,

A friend has 5 more than triple c

Suppose a friend has an "F" number of comic books then,

F = 3c + 5

Hence "F = 3c + 5 is an expression that indicates how many comic books a friend owns".
