Answer:
Step-by-step explanation:
When reducing a number to its lowest term you use the GCF of the denominator and numerator then divide using this number. :
÷
=
The gcf of 75 and 225 is 75 so we divide both the numerator and denominator by 75.

Answer:
<h2>21</h2>
Step-by-step explanation:
The value that is closest
to 85% of 25 is 21 because
85% of is 21.25 and rounding
21.25 to the whole number is 21.

Answer: 1,569.75
Step-by-step explanation:
6279÷4=1,569.75
:)
Y =ax² + bx +c
1) Point (0,7)
7 = a*0² +b*0 +c
c = 7
y=ax² + bx + 7
2) Point (1,4)
4=a*1² + b*1 + 7, ----> 4 = a +b + 7, ------>
a+b= - 3
3) Point (2, 5)
5=a*2² + b*2 + 7, ----> 5=4a+2b +7,---> -2=4a+2b, ---->
-1=2a + b
4)
a+b= - 3, ----> b= -3 - a (substitute in the second equation)
2a+b= -1
2a - 3 - a = -1, ----> a - 3 = -1,
a =2
5) a+b= - 3
2 + b = -3
b = -5
y=2x² - 5x + 7
Answer:
Required solution (a) 
(b) 40.
Step-by-step explanation:
Given,
(a) Let,
Then,
Integrating 
we get,
Differentiate this with respect to y we get,
compairinfg with 
of the given function we get,
Then,
Again differentiate with respect to z we get,
on compairing we get,
(By integrating h'(z)) where C is integration constant. Hence,
(b) Next, to find the itegration,
