Just plug it in:
c & d = c² + d² - 4
2 & 1 = 1² + 2² - 4
= 1 + 4 - 4 = 1
Answer:
False
hope this helps and sorry if its wrong :(
Just think of 4/8. Four is half of 8, right? therefore, it is 1/2. 4/8 reduced is 1/2
Answer: 4 x (8 + 5) = (4 x 8) + (4 x 5)
Step-by-step explanation:
multiply the 4 by what is in the ( )
4x8 = 32
4x5= 20
so it equals what is on the other side (in the blanks, you just plug in the 8 and 5)
so it would be
4 x (8 + 5) = (4 x 8) + (4 x 5)
25 x 4 equals 100. and 250 x 4 =1000. so one fourth of 1000 is 250.
