We know that a positive number where only one and itself divide it is called a prime number. A positive number with divisors other than 1 and itself are called composite numbers.
Hey :)
The answer is 4x + 6
−2x + 11+ 6x −5
Combine −2x and 6x to get 4x
4x + 11 −5
Subtract 5 from 11 to get 6
= 4x + 6
Hope this helps :)
Answer:
3
Step-by-step explanation:
Points A and B lie on the horizontal line y = 1. The length of segment AB is then the difference of the x-coordinates of the points:
5 -2 = 3
The length of side AB is 3 units.
what in the world is your teacher giving you is my question.
i dont understand either
Let's call the distance from the beach to the playground x.
Let's call the distance from the stand to the parking lot z.
Let's call the base of the biggest triangle in the picture (from the parking lot to the left) y.
Recall the pythagorean theorem: the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.
There are three right triangles we can work with.
Triangle with sides 48, x and z. Here z is the hypotenuse so we get the equation
Triangle with sides 27, x and y. Here y is the hypotenuse so we get
Triangle with sides z, y and (48+27). Here (48+27) is the hypotenuse so we get
. That is,
We have 3 equations and 3 unknowns (x, y and z). So let's take the last equation:
and replace
and
using expressions that contain an expression in terms of x from the first two equations we came up with.
That gives us:
which we solve for x as follows:
Now that we know x we can substitute 36 for x into the equation
and solve for z as follows:
This means that the distance from the beach to the parking lot is 36 m and the distance from the stand to the parking lot is 60 m.
