Answer:


Step-by-step explanation:
is the expression given to be solved.
First of all let us have a look at <u>3 formulas</u>:

Both the formula can be applied to the expression(
) during the first step while solving it.
<u>Applying formula (1):</u>
Comparing the terms of
with 

So,
is reduced to 
<u>Applying formula (2):</u>
Comparing the terms of
with 

So,
is reduced to
.
So, the answers can be:


Answer: X- 0,1,2,3,4 and Y-0,6,12,18,24

Answer:
312
Step-by-step explanation:
because when you add the triangles and rectangles together you get 312
10,800 :) 8 multiplied by 1,350 would give you 10,800 miles.
Factor the equation into...
(3b+5)(3b+5)=0
Each factor 3b+5=0 so 3b=-5 so b=-5/3
Check:
9(-5/3)^2+30(-5/3)+25=
9(25/9)-50+25=
25-50+25=0
It checks,
So answer is A.-5/3
