This is the answer the picture below hope this help
To solve this you can subtract and you get 6
the distance between -7 and -1 is 6
Constant of proportionality is the constant value of the two proportional quantities, in this problem p and s, where 4 is the factor of proportionality because it is constant or k.
In simple terms, p is in direct proportion to s wherein the increase or decrease in value of s results to the increase or decrease in value of p with 4 the only factor remaining unchanged.
In the above problem, the number 4 is derived from the word square. We all know that a square has 4 sides of equal lengths, therefore, the perimeter is equivalent to the product of 4 and its lenght.
The measure of <TRS and angle d are 70 and 43degrees respectively
<h3>Triangles and angle</h3>
The given triangles are isosceles triangles since they have two equal sides.
14) From he triangle RST
<TRS + 90 + 20 = 180
<TRS + 110. = 180
Subtract 110 from both sides
<TRS = 180 -110
<TRS = 70 degrees
15) For this triangle;
d = 86/2
d = 43 degrees
Hence the measure of <TRS and angle d are 70 and 43degrees respectively

That is you can divide both side by the same number to get the answer
that would be 5x=30 because you divide both sides by 5
answer is A
