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
Answer:
Step-by-step explanation:
if n is a positive integer then 4^n has last digit 4 or 6
we choose any number having 4 digits whose sum is divisible by 3 and last digit is 4 or 6.
1014,1026,1104 etc.
Answer:
What is the missing number when n = 1.5?
5n+___=8.89
Answer:
-7/5
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 1-8)/(7-2)
= -7/5
