Answer:
216 cubes.
Step-by-step explanation:
The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.
Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.
Hello,
Let's be a the greatest number, b the smallest
Method 1:
a+b=37 ==>b=37-a
a*b=36==>a(37-a)=36
==> a²-37a+36=0
==>a²-36a-a+36=0
==>a(a-36)-(a-36)=0
==>(a-36)(a-1)=0
(a=36 and b=37-36=1) or (a=1 and b=37-1=36) but a>b ==>exclude
==>a-b=35
Method 2:
a*b=36
a+b=37 ==>(a+b)²=37²
(a+b)²-4ab=37²-4*36
==>a²+2ab+b²-4ab=1225
==>(a-b)²=35²
==>a-b=35 or a-b=-35 (to exclude since a>b)
Answer:
Make N alone
There is an 8 so we subtract 8 from both sides so the equation is still equal
-4 - 8 = -12
Because we are subtracting N it is positive
N = 12
8 - 12 = -4
Hope this helps
Step-by-step explanation:
10-25x=5
subtract 10 from both sides so 5-10 is -5
so now your left with -25x=-5 then divdie -25x by -5 and rememeber -5 divided by a negative is a positive and positive divided by a posivte is a positive and negavite divided by a positive is negavtive or positive divided by a negative is a negative
so when you divide -25x by -5 you get 5 so your answer is x=-5
