For 175 : 250 divide them both by 25 to get
<
25 goes into 175 > 7 times > 25 into 250 is 10 times! >
For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us
.
8 goes into 16, 2 times and 40, 5 times.
Answer:- 2
Step-by-step explanation:
Answer:
True, A
Step-by-step explanation:
If you sum two different sides of a traingle it must be greater than the remaining one
We can test that by adding the two smallest sides
1+8=9
9 is obviously greater than 8, so the answer is: true

Explanation:
Given:
x
2
+
10
x
+
16
=
0
To complete the square put the two
x
terms on the left and the constant on the right of the equation:
x
2
+
10
x
=
−
16
Complete the square by multiplying the
x
-term by
1
2
:
1
2
⋅
10
=
5
and adding the square of this number to the right side of the equation:

.
The
+
25
was not in the original equation. If we add
+
25
to one side of the equation, we must add the same amount to the other side of the equation to keep it balanced.
(
