Simply cross multiply:
18*m = 6*15
18m = 90
m = 5
The greatest common factor of 19x7 AND 3x5 is: X5
hope this helps
The lines are reciprocal because they cross to form an X. Also 4/5 is the reciprocal of 5/4
Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.
Answer:
15 inches
Step-by-step explanation:
Suppose length of original square is L inches.
Now, to form a new square the length increases by 2.5 inches
So, new length=L+2.5 inches
Given that, perimeter of new square =70 inches.
Formula:-
Perimeter=4*length of square
Therefore 70=4*(L+2.5)
70 =4 L+10
4 L=60
L=15 inches
