Answer:
-5 = -9
-2 = -6
0 = -4
4 = 0
Step-by-step explanation:
You substitute each value for x and then solve the equation. (Please give me brainliest)
Answer:
Yes it is!
Step-by-step explanation:
If you want to know whether it is, use the pytheoream theory. a2+b2=c2
a is the shortest side, b is the second longest and c is the longest.
In this case, the equation will be:
8 sq + 15 sq = 17 sq
64 + 225 = 289
= It is a right-angled triangle!
Ok, so if you’re saying -18=r-3, then first you need to add 3 to each side so you can move the 3 with the -18 so you can isolate r. (Leave it by itself). So now your equation is -18+3=r. Next, combine like terms, so do -18+3, which is -15. Now you have -15=r, so r is equal to -15.
Yes, a common denominator is just the smallest multiple of all numbers in a group.
So the common denominator of 4, 8 and 12 would be 4, because 4 goes into all those numbers.
