Answer:
x + (4x-6) • 2
Step-by-step explanation:
First, let's start by calling the width of the rectangle x
Because the length is 4 times the width minus 6, the equation for length will be 4x-6
The width and length together will be x + (4x-6)
You then have to times it by 2 to find the whole perimiter.
This is a problem of
fact families, but <em>what is fact families?</em> Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by w<span>riting the <em>subtraction fact two ways</em>. So we have:
</span><span>
First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:
</span>Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
So I want to take away 3 triangles, then by taking away 3<em> what is left? </em>Well the answer is 7:
Δ Δ Δ Δ Δ
Δ Δ
That is, if we subtract 3 from 10 then the result is:
Second way. In this subtraction we take the same 10 triangles:
Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
Now I want to take away 7 triangles, then by taking away 7 what is left is 3:
Δ Δ Δ
That is, if we subtract 7 from 10 then the result is:
Answer:
Distance from the point to the line will be
Step-by-step explanation:
We have given the equation of the line is y = 2x\
So the equation of line will be y-2x = 0
Point from which we have to find the distance is (-2,1)
Distance from a point to line is given by , here A = -2 , B = 1 and C = 0
And point x = -2 and y = 1
So
So distance from the point to the line will be
Step-by-step explanation:
can you elaborate on this problem a bit more? I just want to give you an accurate anwser
Answer:
7 yellow triangles for each blue triangle
Step-by-step explanation:
the ratio of yellow triangles to blue triangles is
42 / 6 or
(42/6) / (6/6)
7 / 1
7
