First we need to find the base and height of the triangle. We can see that the base goes from 3 to 11 on the coordinate plane. If we take 11 - 3, we get 8.
8 is our base. We can also see that the height goes from 3 to 12. 12 - 3 is 9, so our height is 9.
The formula for a triangle is (1/2)bh so 8 x 9 is 72, and 72 times 1/2 is 36.
The area of the triangle on the coordinate plane is 36 units

Simplify: 3x2 - 4x - 5x2 + 8x

olga55 [171]

For this question, all you have to do is combine like terms. I am assuming that the 3x2 and 5x2 are exponents, so they are one pair and then -4x and 8x are the other. The rule is the higher exponent goes first, so here is what it looks like:

3x2 - 4x - 5x2 +8x

First combine the numbers with exponents, 3x2-5x2, you always bring over the positive or negative, which ever it may be, in this case, since it is -5x2, you bring that over.

3x2-5x2=-2x2

Now to do the number with matching letters, -4x+8x= 4x

Now just bring the problem back together:

-2x2+4x

That is your simplified answer: -2x2+4x.

Find the area of the four walls of a cubical room whose side measures 5m. Find the cost of white washing the room at the rate of

NikAS [45]

We know that one wall side is 5m.
To find the area of one wall, we do 5²=25m²
We know there is 4 walls. So we have to find total area of all four walls.
Which is 25×4=100m²
To find the total cost of white washing the room, we have to do:
100(total area)×23(cost per m²)=$2300
So the total cost of the area is $2300

An arithmetic sequence is a linear function whose domain is restricted to the set of non-negative integers.

Tom [10]

<h3>What is sequence ?</h3>

A sequence is a set of the objects or numbers in a specific order.
It is a function whose domain is a set of natural numbers or non-negative integers i.e. {1, 2, 3,..}
Sequence and series is one of the basic topics in Arithmetic.
An itemized collection of elements in which repetitions of any sort are allowed is known as a sequence, whereas series is the sum of all elements.
An arithmetic progression is one of the common examples of sequence and series.

"An arithmetic sequence is a linear function whose domain is restricted to the set of non-negative integers."

The general form an arithmetic sequence is:

$a_{n} = a_{1} + (n- 1) d$

The function is linear.
The sequence consists of either numbers that are increasing or decreasing based on the value of d, the common difference.

So, the statement provided is True.
