Answer:
Step-by-step explanation:
a) 3 x 5
b) 15 Celcius
First lets work out the length of the top side which joins the points (-1,7) and (-5,5):-
this = sqrt ( (7-5)^2 + (-1 - (-5)^2 )
= sqrt (4 + 16)
= sqrt 20
Now find length of the longer side which is distance between the points (-1,7) and (4, -3)
this is sqrt ( (-1 - 4)^2 + (7 - -3)^2)
= sqrt 125
Area of the rectangle = sqrt 20 * sqrt 125
= sqrt 2500
= 50 units^2 Answer
Answer:
1 1/8 or 9/8
Step-by-step explanation:
5 1/2-4 3/8= 1/ 1/8
Answer:
A 3
Step-by-step explanation:
Let n = the number
a number decreased by 12
n-12
This is equal to 3 times the opposite =
3 times the opposite
3*(-n)
-3n
Setting the two parts equal
n-12 = -3n
Subtract n from each side
n-n-12 = -3n-n
-12 = -4n
Divide by -4
-12/-4 = -4n/-4
3 =n
440000 is the answer because any thing under five turns into a zero and goes down
