How can I factorise expressions

Answers

Answer 1

Answer:

The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.

In a school of 310 students, 70 of them are in the drama club, 190 of them are in a sports team and 50 students do drama and sports. Find the probability that a student chosen at random isnt in the in tje drama club or the sports team

Answers

The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

Let's denote students in D = in the drama club , S = in a sports team

P(D) = 70/310

P(S) = 190/310

P(D and S) = 50/310

P(D or S) = P(D) + P(S) - P(D and S)  

P(D or S) = 70/310  + 190/310  - 50/310

P(D or S) = 210/310 = 21/31

P(neither D nor S) = 1- 21/31

P(neither D nor S) = 10/31

The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

Given, Milo wants to roll epoxy on his garage floor.

The measurements are 20 + √3 feet by 20 + √3 feet.

Therefore, The area of his garage floor is,

= (20 + √3)×(20 + √3) ft².

= 400 + 20√3 + 20√3 + √3×√3 ft².

= 400 + 40√3 + 3 ft².

= 403 + 40√3 ft².

What is Rectangle?

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°).

A rectangle has equal and parallel opposite sides.

A rectangle has two dimensions—length and width—because it is a two-dimensional form. The rectangle's longer side is its length, while its shorter side is its breadth.

We have a figure of rectangle whose length = 10 + 2x or 18

and width = 10 or 2y+ 4

As, we know the opposite sides of rectangle are equal.

So, 10+ 2x = 18

2x = 8

x= 4

and, 10 = 2y+ 4

2y= 6

y= 3

So, the value of y is 3.

Simplified the expression write your answer as a power

Answers

Answer:

2^8/3^8

Step-by-step explanation:

When multiplying powers with the same base, add the number in the exponent. For example, if you were multiplying 2^4 and 2^3, you would add 3 and 4 (3+4=7), and write your answer as 2^7. In this case, the bases being multiplied are both 2/3, so you can add 2 and 6 for a sum of 8 and put 8 as the exponent: (2/3)^8. The fully simplified expression is 2^8/3^8 because the exponent applies to both the numerator and the denominator.

The distance y (in miles) that Train A travels in x hours is represented by the equation y=68x . The graph shows the distance that Train B travels. (0, 0) and (1, 64).

Answers

Answer:

For train A, the distance traveled as a function of time in hours is written as:

y = 68*x

For train B, we know that it's equation passes through the points (0, 0) and (1, 64)

Remember that:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Then the slope for the equation of train B is:

a = (64 - 0)/(1 - 0) = 64

Then equation of train B is something like:

y = 64*x + b

Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:

0 = 64*0 + b

0 = 0 +b

then b = 0

This means that the equation for train B is:

y = 64*x

Where again, y is the distance in miles and x is the time in hours.

If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.
