Answer: 3 times the sum of r and d squared minus 2 times the sum of r and d squared
we write the statement in terms of expression
⇒3×(r+d)²-2×(r+d)²=y
→y=(r+d)²
Answer:
Re :3

A point that is their point of intersection.
ANSWER
or 
EXPLANATION
For 
We make y the subject to obtain,
We can easily graph this function, because we just have to transform the graph of 
by shifting the intercept up to 
.
As for the straight line, 
,
We find the intercepts as follows,
When 
.
When 
.
We plot the points 
and
.
We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be
or
See graph
6.) constant = 75
7.) open sentence = 6 + 22 = 28
8.) equation = 17 + b = 47
9.) solution = when x + 37 = 62, x = 25
